It’s not impossible for a concept like this to work. GirlGamers on Reddit allows men to comment, but not make posts, and the men there are on the whole very respectful. You would occasionally get a toxic guy, but it was pretty infrequent and the moderators removed those comments quick. There are also a lot of moderators on that subreddit.
However, lemmy has a really peculiar monoculture of men who are left wing, but either get extremely defensive whenever someone brings up feminism or are actively anti-feminist.
Case in point: I feel like that group you mentioned kind of already exists, and it’s witchesvspatriarchy, which gets brigaded by angry men on the regular, to the point where it’s sometimes difficult for that community to operate as it was originally intended. I would be concerned that it would turn into a space where women get drowned out by large brigades of men in the community, and it just becomes an echo chamber where men criticise women and feminist thought; it would be an open fire hose for any moderator on that community.
So I’m just not sure if it would work on Lemmy. At the very least, not until more women start using the platform.
Broadly speaking, kiwifarms is also a community where men comment on mirred posts from other social media sites, which tells me that it’s potentially a disaster waiting to happen.
I’d live in fear of men crossposting to make fun of or criticize things I write without my knowledge.
