Alright, relativism says this:
"There are no absolutes. The individual decides what right and wrong are and no one can tell them that they're wrong. If it's right to the individual, then the individual can't be judged for doing it."
(Some of you won't understand this and that's OK.)
Let's say that people's choices are their own personal "laws". Relativism says that I'll make my laws and live by them. There are no universal laws that everyone must follow, because not everyone agrees on what right and wrong are.
FALLACY
Relativism contradicts itself because it says that there are no universal laws, but that in itself is a law. If there's no universal laws, then you can't tell me about your law that says "there's no universal laws" because you'd be contradicting the very premise of your argument.
That's almost as stupid as evolutionists carbon-dating methods. "Well this fossil is 20 billion years old."
"How do you know that?"
"Because it's in the 20 billion year old layer of earth."
"How do you know how old that layer of earth is?"
"Well, it's 20 billion years old, cuz this 20 billion year old fossil was in it."
When I have time, I'll totally dismiss evolution, too.
