I think Sarkeesian’s on a hiding to nothing, trying to change society by removing homophobia and gender-based language from our swears. After all, we (most of us who do the swearing thing; I’m sure there are exceptions) all use “fuck” as an exclamation and intensifier, which word should describe a loving and tender act between two or more individuals who have come together to share something something, etc, and shouldn’t have anything to do even metaphorically with whatever we’re swearing about.
As a Brit, I use the c-word to describe awful people, and I typically don’t use it to describe female genitalia — but even I can’t deny the sexist root of the awful-people meaning. But I’m not going to change it, because it’s an enormously satisfying way to describe someone: that hard K-sound and the almost-spat T at the end, it’s just got good mouth-feel and sounds like an awful person. On the other hand, I am more careful about who I’m using it in front of these days. I would try not to use it in front of the Queen, my sister or Sarkeesian, forex. (Or type it here, as you can see.)
Similarly, while Colbert’s “cock-holster” joke is based partly on homophobia — or at least my reaction to it is partly based on the homophobia of the society I’ve spent fifty-plus years in — the joke is also about a sex act which can be read as a strongly submissive/dominant one, especially in the purported relationship between Trump and Putin; the use of “holster” implies that Trump is very much the sub in that relationship. So I laughed because there are elements of homophobia in me battling with my SJW aspirations, but also because the President of the United States shouldn’t be sucking anyone’s cock, least of all the President of Russia’s. Not even as part of a loving something something, as above.
Sarkeesian can disapprove of such horrible memes, of course, and I can’t say she’s wrong to do so, but disapproval of swearing hasn’t done anything to remove it from general society, ever.
Bonus picture: Gerald Scarfe’s '60s cartoon of Prime Minister Harold Wilson trying to kiss President Johnson’s arse. Is one’s reaction to it mainly homophobia or is it about an unflattering characterisation of the relationship between the two (and by metonymy, their countries) as well? And at this level of symbolism, is it a fool’s errand to try to unpick the two threads?
