Most people in radfem groups aren't even radical feminists, they just found their way there because of being gender critical, because of reaching peak trans.

Most things discussed in those circles are male violence and sexual abuse, exploitation, objectification, etc. No one is really talking about about any actual concrete plans to bring down the patriarchy or end capitalism or whatever. They are just women fed up with the treatment they have received at the hands of men in their lives. Most other feminist groups center men - transwomen, or are pro-prostitution and pro-porn, etc, so women find their way to radfem forums. Radfem circles really aren't that radical.
