A pretty small place but they look serious. /r/redflag

For those who don't know there's a bunch of socialists and lefties on the /r/MensRights sub and it's often remarked that all the so-called socialist subreddits have been taken over by feminists who act like all of these places are /r/feminism -- ie they instantly ban anyone who criticizes feminism. This is part of how feminists try to control the discourse everywhere they go. People often ask if there's any socialist sub that is infested with feminist thugs.

Well /r/redflag seems to be such a subredit.
