What do you all do on days like this?
"Feel" your anger... .and find a productive place for it. We all have legitimate reasons for anger... I try to "use" it to "fuel" my determination to undo years of bad dynamics and to push through the associated stuff that goes with that.
IMO... .the best way to deal with a passive aggressive person is to be direct and calm.
"Hey... .it would mean a lot to me if you would help me when I'm struggling and I've asked for help. I am interested in your thoughts on sexism and feminism and would hope, going forward, you can share those with me at a time when I can give them my full attention."
When you have had it and want to tell them off... .do so succinctly and then disengage.
