A person was chosen because of their identity and was assaulted in a very horrible way because of it. That is a hate crime.
My only beef with the notion of hate crimes is that it is too often applied in one direction. If an angry transvestite were to select a target because he was a straight male, it would ALSO apply, but probably wouldn't be prosecuted accordingly.
In this country, blacks, especially, get away with hate crimes because the same principles applied when they are victim are not applied at all when they are the perp.
