From what I can gather from the article, if you use the phrase “if you know what I mean” about a gay person, then that’s bad. It doesn’t matter if “if you know what I mean” means “because you know that all left handers stick together” or some other characteristic that has nothing to do with sexual orientation. Simply using the phrase “if you know what I mean” must, simply must, mean “because they’re all gay, you know.” Because, you know, everyone will use whatever excuse they can to persecute gays, if you know what I mean.
