Many non-western nations traditionally had third gender (Hijras in India, Kathoey in Thailand, many Native American Two-Spirit Identities). When these places were colonized these identities were used as a justification, and generally punished harshly. The argument that "only people in western nations tolerate this", is bad-faith, and doesn't recognize that anti-trans hostility in a lot of the non-western world was largely created by the colonial overlords this argument is meant to rebuke.
I don't think you know a lot of the meanings of words you're using. Firstly "TERF" ideology is pretty new and not the "traditional position of gender debates." It branched off of recent feminist movements. Most of non-western countries are not TERFs, probably not even feminist by most current definitions, and definitely not radical.
This definition also excludes:
* humans with one X chromosome (1 per 2000 to 5000 humans born [1])
* humans with three X chromosomes (1 per 1000 women born [2])
* infertile women (6% of married women under 45 in the US [3])

Re infertility, don't be silly. Yes I didn't word it perfectly, I meant "XX, i.e. the sex that bears children in mammals". Do you know what anisogamy means? This stuff wasn't complicated 20 years ago and funnily enough the science hasn't changed.
There are fertile XY females among mammals (including humans.)
But in any case, the point is that biology is messy and always has rare exceptions. As an engineer I’m sure you appreciate the value of simple definitions that capture 99% of the diversity accurately.
Not everyone outside the West is a feminist, much less a radical feminist, trans-exclusionary or not.
(Though, to be fair, most people accused of being “TERFs” are at most moderate bourgeois feminists rather than radical feminists, but still even that is pretty unusual in lots of non-Western countries.)
There's no analogous question regarding homosexuality.
They in fact have in the past.
Also? There are trans women who say I'm a trans woman who hides behind nonbinary to avoid the difficulty of transitioning. That position is just as harmful and ignorant, and I still fully support binary trans people. That some people are butts is not an excuse to dismiss an entire group of humans.
But yes, if the activist community fails to disassociate itself from / speak out against radicals who are harming people, then that activist community is going to receive criticism.
I sort of agree, in that the groups are composed of individuals and it's not entirely fair to hold them responsible for things they didn't personally do. I also think if you see a political community as having some sort of problematic culture it's reasonable to say so.
