I'm not exactly sure where you draw the difference. Minority opinions are sometimes helpful in creating products that work for everyone (my favorite example here being a hand dryer that did not recognize black skin). It can be useful to amplify such voices. If you want to call that "SJWism", fine.
But this is literally just a call for civility, recognizing that many people may not want to subject themselves to this kind of toxic atmosphere. You can ALWAYS voice your concerns in a productive manner in the "meritocratic" ideal.
Added to this, note that the attack surface for such toxic behavior might be much bigger if you're a minority group. Let's take the assumption that women need every fucking thing explained to them - which is quite alive and really fucking annoying. I don't think that's banworthy, but certainly noteworthy and, if you wanna continue to talk down to your peers, maybe you need a break from the mailing list after all.
