Catcalling is a good example. When I was early on in transition catcalling felt uncomfortable, but I'd often walk away feeling like someone saw me as an attractive woman, which was a new validating experience and ultimately that outweighed the discomfort. After some more time, now that that's more common, the validation has worn thin and now it's just uncomfortable.

Trans women conforming to traditional gender norms in order to be more accepted by society/to feel internal validation because those things are they they grew up thinking a woman should be like, is what they mean

I.e. the housewife, traditionally "feminine" activities, having somewhat backwards thoughts about a woman's "purpose"
