"Unfortunately, straight white males are not usually very self-aware". Based on what evidence? It comes across merely as prejudice. (I wouldn't feel that strongly about it if I hadn't then seen her conversation with Amanda Rutter on Twitter, where she spent plenty of time calling her "Whitey", which enforced my opinion on this point.)

While I agree that there probably are many straight white males who (perhaps wilfully) haven't examined their opinions on such matters, I think that most of us today cannot avoid that kind of reflection. If we're interacting with the world at all, then the issue is constantly in front of us, and at least some soul searching will have taken place.
