Strategy number one:
Refuse to accept that the writer’s experience of the world can be different from your experience as a straight white guy. Demand proof of their assertions but only from sources that you deem credible. Focus on details and find flaws instead of looking at their overall argument. Redefine terms until they mean what you want them to mean. Explain why the writer’s experiences don’t mean what they think they mean. Generally rationalise and explain and squirm until you’ve made the uncomfortable idea of prejudice disappear. Be ostentatiously reasonable and rational. If the writer resists, tell them they’re being unreasonable, unlike you. Do this repeatedly and at great length until you’ve smothered the life out of the conversation and all the other commenters give up, thus allowing you to claim that your superior powers of reason have won the day.
Strategy number two:
Explain that you’re a straight white guy and you’ve experienced prejudice/oppression/violence/whatever, so therefore, the writer’s claim that the abuse/aggression/harassment they’ve experienced is different in kind or intensity or frequency from your experience is invalid. Assert that we’re all victims here and that women don’t have it any worse or different than men.
Strategy number three:
Say that you’re a straight white guy and you’re not a sexist jerk so why are all the women picking on you. Demand praise and affirmation for your goodness from the writer and other commenters. If you don’t get it, claim that straight white guys are the true victims here.
These tropes turn up with depressing frequency any time anyone posts about what it’s like to be a woman on the internet, at work, in the world generally. The conversation inevitably turns into howls of anguish from assorted men doing whatever they can to deny that sexism exists, that women’s experiences of the world differ from theirs, that the world is not the same for everyone, and that straight white men get to be the norm from which the rest of us deviate. It’s tiring.
