Don't know where you get that idea, honestly. A lot of trans people certainly think that, but there is definitely no consensus within the trans community about the definition of gender. Personally I even subscribe more to performativity (mostly as described by Judith Butler) than any other theory. But also I don't care that much about gender philosophy.
My "transgenderism ideology" is quite simple: other people's gender or presentation is none of my business and everyone deserves the same basic human rights. If that's dogma, okay I guess
I assume you mean medical transition, since socially transitioning--such as by changing your name and pronouns--would generally be considered performing a gender even if that doesn't involve changing things like clothing and behaviours (e.g. cis tomboys and femboys exist and are performing the gender they were assigned at birth, just not in a typical way)
Next transgenderism dogma: Socially transitioning being a thing.
I don't believe that wearing specific clothes and demanding she/her pronouns from other people makes me less male than i happened to be. Or more female. Nor do i believe this applies for other people or sex swapped.
> just not in a typical way
We are in a post-enlightenment democracy. You can just do atypical things. And it doesn't make you more or less female or male or transitioning or anything like that. Not everything will fit into words, but that's the nature of things.
> You can just do atypical things. And it doesn't make you more or less female or male or transitioning or anything like that.
...yes
That's why I said cis tomboys are still girls and cis femboys are still boys (not sure what the enlightenment or democracy have to do with this discussion)
> I don't believe that wearing specific clothes and demanding she/her pronouns from other people makes me less male than i happened to be. Or more female. Nor do i believe this applies for other people or gender roles swapped.
I can see this discussion won't go anywhere if you're not willing to justify your beliefs, and if you're going to continue insisting that trans people are a monolith. And at the same time imply the tired and untrue claim that trans people deny biology (no one thinks swapping clothes changes your sex characteristics). When we say socially transitioning, we just mean performing gender in a different way, it's just being contrarion to say it's "not a thing", this is probably one of the few objectively true things about trans people.
And it's contradictory to claim that gender performativity is correct, and then later also claim that your performance of gender does not change your gender. Pick a side
