Wouldn't surprise me. He actually probably has two asl names minimum because he's polarizing, famous, and hearing (if he were Deaf his asl name would just be the one he uses). The Deaf are as unsubtle as the easy jokes would imply. Also he was famously hated in his hometown which has a decent Deaf community. Decent size, probably not behavior, I feel comfortable assuming that Deaf New Yorkers aren't particularly polite representations of either of their communities.
