How are you being discriminated against, exactly? And nowhere did I say sex is an identity (although it is rather arbitrarily assigned, based only on the appearance of genitals when a child is first born). In any case, I was pointing out that the writers of this article are not trans women (nor do they identify as women in any way, as far as I can tell, but I do not know that for sure; you would have to ask them). Not sure what them being men, women, or non-binary has to do with whatever sex they were assigned at birth. From the article, it seems that they were assigned female at birth, so if you feel the sex at birth is the most important thing, you are denigrating people who — at least in your mind — would be female. Also not sure what you might be implying about sex being a “protected” characteristic. Protected from whom? In what way? Who will protect everyone from your hatefulness? And yes, attacking trans people — of any gender — just because you don’t understand (or don’t want to understand) exactly what and who trans people are is rather hateful.
