The human race is doomed, and I don't mean because of enemies of America like Saddam or Osama or George W Bush. Even without war, the human race is doomed, damned, screwed over, and going out of style. Here's why.
We've beaten evolution. Hell, to really give evolution the finger, we've reversed it. In a fun-to-use phrase, we're peeing in the gene pool. Instead of discouraging evolutionary mistakes, we encourage them. We give them disability ensurance, special classes, easier grades, etc etc etc. Back when evolution mattered, cavemen who got injured while hunting would probably die, and would definitely not reproduce. These days they'd get workman's comp, and still have plenty of chances to pass on their lack of skills.
One thing that amazes me is how we hang on to the people who are blatantly obviously evolutionary mistakes. Retards are the prime example of this. You can't convince me in a million years that a retard would have anything to add to the gene pool that outweighs his retard genetics. Still we encourage them by going easy on them. We encourage people to be tolerant, we give them easy schools to go to, then we let them work. Perhaps you know that I'm referring to how the bill to ban retard marriages was shot down in Congress. Damn liberals.
There are other genetic inconsistencies which are way more dangerous, though, because they're less evident and much more likely to be passed on. Retards might not be banned from marriage by law, but come on, how many retards actually have kids? Not many. But other genetic weaknesses are passed on by the bucketload. Take weak vision for instance. Slap on some glasses or contacts, sure. That's been around forever. But these days you can actually get laser vision surgery to entirely remove the problem.
My main example in the past has been people born with tails, and the same goes for them. Instead of being thrown aside, they have the tails removed at birth and go on to pass on the tail gene to their kids. More extreme versions of this may be people born as transexuals (ick). I mean, what if the woman (or man, assuming a chick ever reads this page) you're going to marry was actually born a man-woman and she never tells you, then without knowing it you're responsible for passing on the man-woman gene?
Now that you've heard my arguments, feel free to run out into the streets screaming, then collapse in a gibbering heap when you run out of air.
