While I partially agree with this, it’s a little bit reductionist.

While it’s true that sexual/gender identity is not Inherently coupled to radical politics, the contradictions are clear. Reactionary / liberal trans people are subjecting themselves to a contradiction - the contradiction between sympathy and reality. By being a liberal as a trans person, you are sympathizing with liberalism, and are contradicted with the reality of liberalism - that liberalism at best feels indifferent to transgender people and at worst feels complete and utter disgust for them.

So, it definitely is pushing you towards radical politics if you are not a straight or cis person in the modern day and age.
