I'm not attempting to "psychologize" the guy. He made a flat-out misogynistic comment. I don't know anything more about him than that (well, and the other comments which have been quoted on here). But it only takes a single comment of someone calling someone else a "nigger" in an attempt to demean and exclude them before you can call someone a racist. The same is true here; someone who claims that asking that people be a little more sensitive means that women want to make it all about their vagina is clearly lashing out in the same way.

  The hidden (and incorrect) assumption here is that 
  this is unconnected to PC activism.

I'm not even sure what "PC activism" is supposed to mean any more, or why people consider a lot of things they accuse as being "PC activism" to be negative. Most of the times I've seen it thrown around recently were when people were just asking that other people act more nicely. Apparently asking people to act nice is now "PC activism".

I will welcome debate about how much needs to be codified; I hate policies that say "you can't use these X words" as the next guy. But a lot of what people rail about as being "PC activism" is just like this; asking that people be a little more considerate in naming package they're putting into a public repository.

So, what's an appropriate reaction to this post? Maybe to say "OK, listing 'hoe' in there is overkill, that's just being used as a pun on 'rake'." Or maybe saying "hmm, I'm not sure how useful it is to ask people to be nicer while calling them assholes."

What's not an appropriate reaction? Talking about vaginas and male spaces and banning someone who just made a request to be nicer and listed a few examples of the kind of behavior they were talking about.
