I guess I could put together a more reasoned argument as to why I don't think "That's so gay!", "These college rape statistics may be inflated", and "Greek philosophy is more important than jazz music" are violent, but I don't feel like doing so.
In Latvia I was neighbors with an Indian who was beaten up on the streets of Riga because of his skin color. I saw skinheads attack a gay pride parade in Tallinn. I know people who can't get up in the morning because they were raped. I know people who were severely beaten as kids. I have friends in Sarajevo who suffer from PTSD after living through a genocidal civil war.
Violence is violence.
