I wouldn’t saying trans-phobic because real phobias are stigmatized enough already, and the word removes agency from transmisia/anti-trans. But yes this isn’t a goof thing to say it sounds like they have a lot of internalised hatred toward themself and are using christianity to “escape” their deep shame of themself. But thats not to direct all blame away from christianity here, lv 20:13 straight up commands the genocide of gay israelites, and the only reason yahweh the all loving all forgiving god doesn’t command death for gay people today is because jesus took the death punishment on gay peoples behalf.
