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"
I think the underlying theme meant to be picked up here is it's attention. Guys don't get attention more often than not so when a guy transitions and receives that attention they absolutely love it. Whereas cis women receive this attention from the beginning and it's gotten old to them.
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.
