Friendly PSA to reddit refugees: please be aware that you are on The Queer Website(™). And while I would say the whole blue hair and pronouns tumblr sjw perception many people had on reddit is somewhat exaggerated, it is absolutely true that the user base (at least the part that makes good posts) tends to skew towards non-men and non-cishet people. Which is all to say, it's best if you get into the habit of checking people's pronouns. They're usually found in people's header so it's not really much effort. (And look, I know it was site culture to refer to everyone as "sir" and with he/him on reddit. But not the site culture here, and you're going to make people uncomfortable if you go around he/him'ing people). Or you can always phrase your comments neutrally (coming up with ridiculous neutrals for gendered words is absolutely part of tumblr culture, so go off). But yeah, just don't be an asshole and you'll be fine
