I’m a woman, and make no attempt to hide that fact in my posts. That said, I also don’t personally have much interest in talking about being a woman, so don’t sub to any of those places you linked.
Over on Reddit I just sort of let people assume I was male a lot of the time, since it wasn’t really relevant to what we were talking about. But from the start on Lemmy I’ve made sure to call out incorrect assumptions, downvote and give a talking to people stereotyping or being misogynistic, etc etc. And the more of us (of all genders) that make that same decision, the better things get.
I also mod !knitting which as you might expect is largely although by no means entirely women. Any questionable comments over there are dealt with swiftly, I am absolutely not having it.
I don’t necessarily see it as a “problem” that Lemmy is seemingly male-dominated (I say Lemmy because my Mastodon is very much female-and-NB-dominated). It’s more just a fact of early adopters tending to the techy interests that skew male. But if someone does see it as a problem and wants it to change, there are basically two things to do:
Make sure you’re helping make Lemmy a welcoming place for non-males
Invite your non-male friends
All that said, other women may disagree but I don’t particularly feel like a minority on here and never really think about it until coming across something gross (which is a LOT less often than on Reddit, thankfully). There may be few enough women that I recognise their names often when they post, but let’s be honest Lemmy is a small world and that goes for most regular posters in general.
(And it helps that I’m middle-aged so if any little boy thinks they can upset me with comments about my gender or appearance or whatever, lol, the self-confidence of age is a wonderful thing 😉)
Edit:Just wanted to add, if you’re not a man and you’re reading this thinking “wow she’s lucky, I’ve had such a bad experience here” then first, I’m sorry you’ve had that experience, people suck sometimes. But also, drop me a DM let’s see if we’ve got any interests in common and I can maybe signpost you to some more friendly communities and people. Between my two accounts I spend WAY too much time on Lemmy!
