It would only be ironic if the women of Lemmy were the most powerful people on the platform and used that power to silence men across the website. As it stands, women are a superminority on the fediverse, and men have the numbers to run roughshod on these communities and effectively prevent them from being spaces where women communicate with each other. This is an ongoing concern on c/witchesvspatriarchy, where thread after thread gets derailed from its original purpose by men. The goal isn't to censor you so much as defend ourselves. So it's not ironic.
Especially since c/menslib could make its community men-only and you wouldn't hear any complaining from me.
