Whatever happens we should not have a situation where simple declaration of ones gender gives a right to the services of that sex.
A discussion of how this 'case by case' analysis would work might be more productive than denigrating transwomen outright as so many recent threads have.

I feel the need to point out that you cannot state your first paragraph, without understanding the second.
It's really not interesting, conducive, or a good use of the time of feminists to drill down into the trans-ideology.
It's frustrating, infuriating and depressing.
It's like forcing yourself to look at incel websites. Something we know exist, but, in their case, are fortunately not given much credence.
Feminists are the last people to want to 'denigrate' on a regular basis. Even when they talk about the reason for feminism, the oppression by men, they're very careful to say NAMALT.
But without pointing out that misogynists make up a large part of the trans cohort, the things they say, why they say them and the effect it has, you would just be left with your first paragraph.
You calling it denigration is misleading. Denigration is unfair criticism.
None of this analysis is unfair.
The only unfair part is that we are having to do it in the first place.
