I notice in the comments on David Schlesinger's blog posts about RMS's "EMACS virgin" tangent at Guadec/Akademy a lot of folks telling him to stop being a "pseudo-feminist" or implying that he thinks women are defenseless and need a big strong man to protect us, or whatever.
We don't need knights in shining armor, but we do need allies. For example, if someone has demonstrated that they are a misogynist, do you really think they will listen to a woman when she says that was offensive? Um, no. They'll call her oversensitive and try to blame it on PMS or tell her she just doesn't belong in that group and should go back to her knitting circle. This is where the male feminists come in. Being male, they have a chance of actually being listened to. That is, if they aren't dismissed as gender traitors first. The traitors have to be discredited. And that's why one of the first things you'll see in a comment or hear is that the male feminist needs to stop treating women like delicate flowers who can't defend themselves.
