<p>Also, please note that science (something that we are all, hopefully, learning in college) is all about making generalizations. Every theory, every bit of knowledge that we have is a generalization (which is not always right). </p>
<p>Generalization is natural and essential in our life. If someone starts chasing you with a knife, you generalize that the guy wants to kills you. You don't adopt a liberal position saying something like "Oh, may be this guy is chasing me with a knife because he wants to brag about the fine knife that he has". You run away immediately. If you get a food poisoning at a suspicious-looking cafe, you don't go there for the second time, thinking "I don't want to be prejudiced against this cafe, it's not politically correct". Think about this.</p>
