Oh, god, @jsoosty has been hounded off?
On the privilege thing, schoolclosed, I've never seen it as a thing about what you present as. Some trans women are pretty clearly trans, but others are entirely stealth - it's possible you know trans people without knowing at all they are trans. I know plenty of butch dykes who have at one or other time been taken pretty consistently for men (when they didn't want to be). One of my big sisters spent her teen years, to her utter utter disgust, being called "sonny" in shops, anytime she wasn't uber, uber girly. Convincing gender presentation can be all over the place.
I've often wished I had been raised male, because I see the effect (confidence, a knowledge that they matter, or should matter, their voices should be heard, etc etc) that male socialisation has on men, and I honestly don't think that either men or trans women even realise it's a thing. And that's why I am inclined to cut a bit of slack to trans men who are behaving like arses, because they have to negotiate being trans with a lifetime of female socialisation (be nice, be quiet, be pretty, serve other people). And that's what I think is behind a lot of the extreme trans activism, is people who have a lifetime of male socialisation behind them, are used to being treated like men, and then after they have achieved this thing they want, of transitioning to present as women, suddenly that they have grasped the shitty end of the privilege stick and are horrified. And they cannot imagine that women live with this all the fucking time, so they assume that the worst is happening to them because they are trans, and that - combined with the male socialisation that has convinced them the world turns around their axis - leads us all to where we are now.
So - male socialisation of thinking that they matter and that their voice deserves to be heard, combined with the cluelessness of male privilege not understanding what being a woman is like in reality (you don't matter and nobody cares what you say), leading to hurt and anger and a demand (directed towards women, not men) to be prioritised once again as they "deserve".
Hence why I don't think women's "cis privilege" exists.
