I'm going to say something that I know to be wildly unpopular, but I think it will explain this.

I associate sexism with women being paid less, denied promotion, being touched up, having to "take a joke" in a macho culture, having to fight twice as hard for everything. I'm used to it in the defence sector although to be fair to them, if you can do the job and be part of the culture, you're more respected than in many other walks of life. It's not sexist - it's just brazen, bolshy, and in your face tough for everyone in different ways. But when the really nasty stuff happens, that's when we get pissed and want to chop bollocks off. If one writer, who as good as he is may still disappear into obscurity next year, makes a few crap jokes about the length of a skirt, we're only likely to dismiss it as toss not worthy of our time and move onto beating the shit out of the real bastards. I don't see this as a creep effect because I routinely call unfunny crap like this out to people's faces. And I'm willing to be you do, too.

I've got honest to God battles to fight. I've got no time for the cosmetic ones. (And all that.)
