The sexual mechanisms of the two genders are just not compatible, that’s the horrible truth of it. (...) This is a truth we dare not acknowledge these days - because sameness is our religion and heretics are no more welcome now than they ever were - but I’m going to acknowledge it, because I’ve always felt that humility before the facts is the only thing that keeps a rational man together. Be humble in the face of facts, and proud in the face of opinions, as George Bernard Shaw once said. He didn’t, actually. I just wanted to put some authority behind this observation of mine, because I know you’re not going to like it.
