If you mean communities there are a few. off the top of my head, witchesvsthepatriarchy on lemmy.ca is pretty active. I think there's one called womensstuff, I think im on the blahaj.zone one. From there you can find sister communities.

Are you particularly interested in feminist communities or are you seeing anti-feminist posts in your feed? Genuinely curious; I haven't seen much of the latter myself on Piefed or Lemmy.

what flavor of feminist are you looking for?

lemmy tends to attract more extremist/left versions of everything, including feminism

Others have already answered your question, but I'd like to note that it's timely to ask this during women's history month :p

what?
