He who fucks goats, either as part of a performance or to troll those he deems has overly delicate sensibilities is simply, a goatfucker.
If your goal is to be seen as a racist, and to provoke a response from people who are offended by racists, and you do all of the things that racists do to that end, spending time on racist forums spreading racist memes and hate speech, then the distinction between you being an "actual" racist and your racism being mere performance is one without a difference.Because being racist as a hobby isn't really something non-racists tend to do.
