I mean you can do both. It's not one or the other. In order for women to be safe within the movement you're going to need to address any reactionary views from existing members and potential members. And some of those people will need to be handled different with different approaches. It's just like union organizing. You can't just barge in and say "labor oppression must be stamped out!" You gotta talk to people, feel them out first, and talk to them where they are (without sacrificing your own values of course).
