Right I'm just going to state this.
Violence is not just physical, it can be verbal and psychological and this guy was clearly violent in his rhetoric.
You can state that, but you would still be wrong. Words are not violence. They may be offensive and hateful and make people very angry or hurt, but they are not violence.
I know this is in the context of pushing somebody into a shallow fountain, which barely qualifies as violence at all. Just responding to this particular part of your post.
