I'm ok with being called a racist. And yes, the behavior of the group influences my opinion about them in some degree when I first meet them. Everybody does that every day about everything. You will treat a hot girl differently than some morbidly obese chick. That behavior is hard wired into everybody's brain. It's typically called intuitions and intuitions are based on patterns. If a negative pattern is constructed, is that the fault of the person who constructed the pattern, of based on the actions of those the patterns are built around?
In the case of a morbidly obese chick, you can assume she doesn't take care of herself, eats too much, is lazy, guess that her house is a mess, and has low self esteem. In how many cases is that true? Your brain creates that pattern.
There is nothing wrong with creating a pattern. Anybody who is honest with themselves does this. In fact, your brain does this at a subconscious level, and most people have to fight against it. All I know is if I drive through the inner city, I'm going to be more alert, and nervous compared to driving through a rural area. To call me a retard for being that way, fine, I'm ok with being a smart retard.
