1. Yes
2. NO, because people are very judgemental whether they want to admit it or not. Sometimes they don't even realize that they're doing it.
3. You can't really learn prejudicism, mainly because it is something you have to experience first hand (yourself) or second hand (it happened to someone close to you) (or it happened to you when with someone that's normally a victim of prejudicism)
4. Criminals can't get a good paying job to support themselves and/or their families. This is a big issue because not everyone that goes to jail/prison are guilty of the crime they were accused of.
5. Yes all the time, I'm an immigrant so when I just moved to the U.S there were times when people would assume I don't know what I'm doing/saying because I'm from a third world country. When in reality they were the ones that were behind with the school curriculum. I think it was based on prejudicism because I wasn't from the U.S, so they judged.
