hexbear is heavily transfem and bans aggressively for misogyny/transphobia. Spending some time there when their recent domain crisis defederated from the rest of Lemmy was actually quite relaxing

it's called pinterest

Edit:

PS: Ok so it looks like people here are just as bad as redditors. I was answering the question in the Reddit caption of this post. Pinterest has been known to be an alternative to Reddit (as a link aggregator) which attracts women a lot more than men.

This is a KNOWN thing, check this 10 year old article from the people managing Pinterest stating as much

Of course women are welcome here, there is no question about it. Does it matter if there is an instance for women? I don't even know, I know women who love stereotypical male stuff and vice versa. I assume anyone, male, female or anything in the spectrum, can browse around and collate their favorite subs

Be the change you wish to see in the world.

It really comes down to this: if you want your own space for particular interests, you should create one and find likeminded people to populate it. Just waiting for it to magically appear isn’t going to work. Be assertive.

almost all the subs that "are women" are basically astroturfed by men, or some of them are male users posting as a "woman"

beehaw.org aspire to be nice, friendly diverse and safe. But they're more towards nice, not women. And we have lemmy.blahaj.zone for queer folks. To my knowledge, there isn't a place aimed towards women. Maybe heehaw is the closest... Still not really a fit.

You could go ahead and also ask in some of the women communities, see how they get along here on the Fediverse.

Lemmy is aimed at pleasing all of humanity.

Asking for a women-centric flavor of any site is parallel to asking for a version with less men. If you're implying there is a difference to the interests of both, I'd love to show you the Grey's Anatomy sub.
