I have to say, I'll always stand up for what's right. Judging people by how they look is wrong, period. You can not like how the people in the pictures look but you don't get to ascribe to them all sorts of nefarious characters because of it. You do not know them and know absolutely nothing of their character.
Prejudice means pre-judging. As in judging someone before you know anything about them. If you are judging the people in the pictures based on their looks, you are pre-judging them. You are prejudice.
If you're mad at me because you feel like I might have called you prejudiced then you probably need to do some introspection and look at your own character.
