I don't want this to be an accusation about lemmy's user base, so take this next comment with a grain of salt:
I feel like lemmy slants male the same way early reddit did, and the same way a lot of more technical communities seem to. I've definitely seen threads where the perspectives being shared feel alien and out of touch, and although I'm sure that they have valuable insights about many topics, it does feel kind of... homogenous?
One specific example is the threads arguing about whether to make lemmy more like reddit or not. Often, there are a lot of comments arguing that they don't want to change lemmy in ways that would make it more inviting, because then more people from reddit would show up. The implication is that the average user of reddit is an idiot or should be unwelcome in some way, but to me it seems that they are just trying to select for men in technical disciplines and who have similar world views to the current user base. Idk, it's not a great look.
Anyway, I'm non-binary and I don't have endometriosis so I'm probably not part of the communities you're looking for... still, I wish you all the best looking for your space. I think it's truly less homogenous here than it seems... We'll get more diverse perspectives over time!
