I don’t see how anyone can go through life and not recognize that the idea that race is only skin deep or a social construct is childish stupidity. But regardless of what prejudices you may have toward any given group, the most important thing is that you are able to judge individuals as individuals.
I use prejudice in the broadest possible way, meaning pre judging. Some may be positive- a person wearing glasses may appear more intelligent, one might think an Asian might be a better student, etc. Others are bad but not criminal- a beautiful woman can’t be very smart, or a man can be thought more violent then a female, etc. But very few people are truly racists, I believe. There are even many people who will hold negative thoughts about a group yet treat individuals of that group just fine.
