Not sure where the transphobia is in his Tweet. Do elaborate please. The fact that they are transgender should not make them special. It is no different than a person making a comment on "hey, [insert [u]celebrity[/u] name here] gained weight." The fact that you are making a big deal about it goes to show that you're treating them special for being transgender. Correct me if I'm wrong, but isn't treating someone differently for their race considered racism? If so, wouldn't that make you sexist, OP?
