There's no way. All their 'spaces' on shit like reddit belongs to men. Even websites like lolcow farm are owned by men but ran by women. Sites like spinster.xyz (a Twitter alternative for the gender critical on the Fediverse) are operated by Graham Lineman, IIRC.
I've tried to express this point before but it's a hard sell to both sides. Men have to reduce their woman hatred, and women have to stop distrusting men. At the end of the day, women are necessary for family and a full life, and men are necessary to actually run society. Like it or not, that's how it always plays out. The alternative is our current reality, and it's only going to get worse.
