That would be a massive fumble. Assuming any of us survive, what is forming is an opportunity for a seismic shift in ideology.

Gatekeeping and purity tests certainly won't help

Then why push away people like this? Why not show them the light and introduce them to the things that actually make the changes? You can invent someone who “will automatically go back to the right” in your head but that isn’t always the case in reality.

Sure you could push for it, like people have pushed for it for generations. Pushing for something alone doesn't accomplish it.

Its also in issue in the real world. So many leftists I met were super knowledgeable about anticapitalism and antiimperialism, also put that to practice, but were still misogynistic asshats and cared little for antiracism.

I would argue patriarchy was one of the reasons capitalism was actually able to exist and spread. Plus it also exists in non capitalist societies / contexts.

It’s implied. It doesn’t need to be said.

It definitely has to be said. Manarchists, brocialists and in general chauvinist on the left make it necessary. Because it isnt implied.

It’s much older than that, religion is generally extremely patriarchal and predates capitalism.

I'd generalize it a bit more and say that patriarchy is a result of having rulers.
