Thoughts of Censorship?

If it is for public viewing, then we should be protecting our children from "adult" material. However, if it material that is being displayed for all to see and is offensive, then they should be censored. For example there is "religious" group that sets on our town square holding poster size pictures of aborted fetuses and they literally scream at pers- by (including young children) about how God hates "fags". Those people have no clue about the beliefs of the people they are screaming such things. I don't want to have to explain to my 2 year old what she just saw on their posters(aborted fetuses). I don't believe in abortion, but I shouldn't have to try and explain their poster's away to a 2 year old. There are some things that should be up to the parents to expose to and explain to their children. It should not be forced "before their time".
