Personally, I don't see a difference between combating fascism, and gender rights, gender affirming care, and recognizing people as the gender that they feel most comfortable as. I also don't see a difference between combating fascism and LGBTQIA+ rights in general.
Fascists would have all of those rights stripped away from people. So bring pro LGBTQIA+ and being against fascism, is essentially the same thing in my mind.
The thing about it is, you can be against fascism, but not pro LGBTQIA+, but it would be, in my mind, impossible to be pro LGBTQIA+ and not be anti fascist.
So anyone who wants to deny LGBTQIA+, gender affirming care, or the recognition of people's gender, but who is self-proclaiming to be against fascism, is either under some confused notion of what fascism would entail, trying to find some "middle ground" which doesn't really exist, or they're still fascist, but only if their way of life is what's being promoted under fascism, and we can it something other than fascism.
All of those people can suck my dick.
LGBTQIA+ rights are human rights.
EDIT: I want to add that I'm not LGBTQIA+. I just believe that anyone who is, should have the same rights to be just as happy, or as miserable, as everyone who isn't. I am an ally. I am a humanist.
