None of the above, I tend to judge people from first impressions.. I will meet anyone and not have a problem with them until they say something stupid or act ignorant, then I tend to be rude or "discriminate" if you will..
I think Juana has most of them. Though I would replace Religion with Weight. Most religious groups do not have a set look, i.e. you cannot tell what religion they are by looks alone. The most "popular", and most damaging, of discriminations are based on appearance.
