First of all, please be open minded cause I am not writing this offend anyone, I am writing it because what most of the people want from other people it's against the fucking nature of people, so if you don't withstand some reality you can just move along...
We label because it's easy to do it and because every living thing labels the shit around it: every animal knows what to hunt, what to run of, and who's not in the pack, as well as the Neanderthals and ancient tribes labeled people from out side of their village as enemies. And if you think you're more evolved than the animals just because you have feelings, think again when you go pass that local homeless guy from your area without giving him shit. We are slaves to our instincts.
So this works like this: If you have a bag with 100 beans, and you see that 90 beans are damaged somehow, you throw the whole fucking bag because you, as any other animal, don't have the instinct to analyze the whole bag just to search the 10 good ones. Even further, if you do that, you might find that 1 or 2 beans from the 10 good beans are also fucked but on the inside.
This is what we do with humans also:
I've seen a lot those bullshit quotes, and they are completely retarded, all of them. It's like telling a coal miner that what he does is bad for the environment...well fuck you, he does what he can to survive...
