The US has freedom of creative expression through artwork. I don't think someone should be illegally imprisoned for expressing themselves or harmed. It doesn't make sense to me for people to do so.
When we read, or hear, or look at paintings, we learn. We become more well refined people through them. We're able to think outside the confines of our own knowledge, because we have more of other people's ideas in our mind. When people work in a group we can accomplish so much more than when we work by ourselves.
