In the context of human/animal relationships, let's start with terms used almost exclusively by animal rights extremists:
'factory farm' (a farm) And that could mean anything from a small family farm to a commercial farm, if they want to smear any farmer, they call it a factory farm)
'vivisection' and 'vivisector' (surgery, surgeon, animal research and researcher))
'specism' (looking out for our own species) Animal rights claim this is as bad as racism, but every animal species looks out for its own species first, it is not racism, it's natural)
'canned hunt' (an animal rights myth about shooting animals in cages and the like) If you own a vast amount of property and you shoot a kyote to protect your livestock, you could be guilty of the 'canned hunt'. Or killing your own excess animals could mean that as well. But the animal rights radicals would have people believe that canned hunts as they describe them with animals being put in cages and shot for entertainment is a reality, and a common one.
'jail' or 'prison' (a cage)
The 'murder' of animals - 'murder' is a human killing another human. Only people get murdered, animals get killed.
'cannibalism' when referring to humans eating meat. This is one of the more laughable terms because it's only cannibalism if you eat your own species. But to ar it's cannibalism if a human eats any animal species. Ar does not call it cannibalism if an animal eats a human or some other kind of animal. So, we're 'cannibals' for eating chicken but chickens aren't 'cannibels' when they eat grasshoppers.
'dead animals' or 'dead animal flesh' or 'carcass' (meat) This is designed to make meat eating sound inhumane and gross. Again, it's natural behavior for omnivores, and humans are for the most part, omnivores. There are those who choose to eat only plant matter, and that's their choice, but they should mind what's on their own plate and let other people eat what they like.
'guardian' (pet owner)
'concentration camp' (any facility that houses animals being targeted for a very bad smear campaign by animal rights nuts)
'slavery' (this is a particularly malicious smear against farmers, pet owners, working animal owners, and also a terrible insult on any actual slaves and their human descendents today, just as is any reference to concentration camps, and comparisons to the holocaust is very tastelessly insulting on people who lived through and died in WWII and Hitler's hell.
'those who can't speak for themselves' 'silent victims' or 'innocent animals' Terms used by animal rightists designed to villify any human in any human/animal association, but especially where any animal death is involved. They only care about human death if it can be used to tout their agenda of stopping the ownership of animals.
'cruelty-free' Much as the general public wants to stop cruelty, most good people are definitely against real cruelty, it is prudent to be wary of anybody spouting how 'cruelty-free' they are, because chances are very good they are animal rights radicals. And ars love to tell everyone, though they are very short on actually demonstrating this, how 'compassionate' 'caring' 'cruelty-free' and 'anti-cruelty' they think they are. This is also a put-off as it assumes the rest of us are not anti-cruelty.
The trick is to determine what is real cruelty. animal rights can call you cruel for many things, what you wear, what you eat, what animals you keep and what environment you keep them in. So 'cruelty-free' for them may mean the ending of pet ownership, meat eating, depending on which branch of the ar agenda the particular person or outfit is talking about.
Sincere anti-cruelty and compassionate people never boast about how compassionate they think they are. Honestly caring and decent people hold human rights as precious to them and to others, and only seek to stop real cruelty where it exists. They do not go around trying to dictate how others live and interact with animals based on the animal rights agendas.
'You don't care about the animals.' - Typical ar browbeating of someone who disagrees with them, proves them wrong, or even dares to doubt any horrid tale of animal hell they tell.
The following are animal rights/welfare terms as well, but have managed to be picked up and believed by the general public thanks to shoddy media publicity that touts animal rights dogma as fact, and the sentimental tendency for pet lovers to anthropomorphize.
'adopt' (acquiring an animal for free or purchasing it from another person, breeder, pet store, or shelter) Animals are bought, sold, given away, and acquired. Human children are adopted...
'companion animal' (pet)
'parent/mommy/daddy' (the animal owner) This is exactly the same as calling oneself the animal's guardian but many people think it's cute, failing to realize it is ar to view animals as your children.
'owned by' (as opposed to "I own") Many people think this is cute again, but animal rights dictates that we don't own anything, we are intrudors tresspassing on land the animals own..
'puppy mill'
'backyard breeder'
'Collector'
'horder'
All these terms are meant to paint any individual who is a victim of an animal rights smear or misguided, naive person's zeal to be an animal hero, in the worst light possible. If you have too many cats for your neighbor's liking, they can call you a 'horder'. If you breed your dog even once, you could be smeared as a 'backyard breeder'. If you are an animal breeder, they call you a 'mill'. Even people who don't otherwise buy into the animal rights agenda, jump at any and all chances to call the next animal owner one of these intentionally derogatory ar-invented terms. Everybody loves to tell and believe animal abuse stories, true or not. Some people gossip and hurl these terms around in order to try stomping out their competition. 'I'm selling this animal. Whatever you do, don't go and buy from Breeder b. He's a mill.' Others do it to make themselves feel taller than the next person. 'I love my animals. But look at Owner C, she's a horder and abuser!' 'Look at me, I just RESCUED 1000 horribly abused and neglected animals from Person D.' 'A warning about buyer E: she's got too many animals, she's a collector and can't possibly take care of any more.' 'Don't sell to her!' While some true 'horders' or 'mills' may have existed in the past, they never were as common as the animal rights extremists want people to believe, and certainly an abaration from the norm. You can even get slapped with the 'mill' term if so much as one of your animals has an infirmity or a condition. A 'rescuer' could slander you as a bad breeder or owner if one of your cats has an eye or ear infection.
'innocent animals' Highly emotional term used by anybody including non-hard-core ars stricken with pity. Animals don't come 'innocent' or 'guilty' these are human atributes.
'global warming' (animal rights/eco/environmental climate myth designed to scare people and put the blame on humans as usual for the terror of the greenhouse effect.(
'greenhouse effect' 'greenhouse gasses' (all part of the global warming myth touted by animal rights and environmental extremists.) All too frequently believed by the general public, thanks to the media eating right out of the hands of the radicals again.
