I think tattoos are very personal. I know a lot of people who really like them and think that they are a piece of art, or a symbol that has a great meaning. They just identify with that particular design. Sometimes it can be religious, or they need to have one to become a member of a group like gangs, for instance. These people are proud of them and nobody will make them change their minds.
On the other hand, there is a big percentage of people who just hate tattoos and feel very disgusted by them. They think that they are very bad and relate them with lower class, uneducated or criminal people. Some people who got tattoos in the past feel that they made a mistake and have experienced rejection by society. They try to have them removed. Sometimes that can be unsuccessful because of time or because the type of ink the "artist" used can be very hard to remove. Anyway, I don't like tattoos even though I have seen very beautiful ones. I am not attracted to them, and I hope my kids won't get any...I would die!
