We unfortunately seem to be going through a few decades in which hetero white males are seen as legitimate targets for all manner of sexism and bigotry. This was unacceptable back when men were treating women and minorities in such a way, and it is no more acceptable today merely because the polarity has been reversed. Before writing or saying anything, it's a good habit to insert an emotionally laden noun in place of "man" or equivalent signifier and then see how you feel about it. The world is not going to get any less toxic merely because we alter who we direct our bigotry and sexism at - especially when we're not even aware we're doing it. Hence the "insert Jew or Negro or Woman here" test - it's very revealing.
