Trans is also an ideology. It's the belief that each person has a "gender identity" which may or may not align with their sex, and that this "gender identity", rather than sex, is what makes someone a woman or a man or, somehow, neither.
By the same logic as you are presenting, it is toxic and hostile to impose this ideology upon others. If believers of this ideology want to use "preferred pronouns" and such, they should of course be free to do so.
But others who do not hold this ideological stance, including those who oppose it for whatever reason (e.g. because they see the concept and implementation of "gender identity" as fundamentally sexist), shouldn't be forced to pay lip service to it, any more than atheists should be forced to pray at work.
You call this refusal "assholery", but presumably that is because you are a believer of this ideology - including the belief that to reject it is "transphobic" (which is roughly equivalent to the religious zealots' cry of "heretic") and therefore, per this belief, reprehensible?
