because their view is simply (if translated into the correct parlance): “People should not receive hormone replacement therapy that is contrary to the gender they were assigned at birth”.
Anecdotally, I have never once heard anyone express this opinion. It's always been hard no on any form of gender affirming care, hrt is evil, that sort of thing.
While this is CLEARLY their actual beliefs, it's not their stated view.
Similar to "the only moral abortion is my abortion" hypocrisy.
Understandable.
It's a fairly middle-of-the-road, while being catchy and therefore played all over the place.
I've felt similar about a lot of popular songs in recent years. They just feel bland, but some parts still get stuck in my head every so often.
