It doesn't matter how well you can cope, it doesn't matter how little dysphoria you think you have, it doesn't matter how well you pretend you can repress it.
If you are trans, the call of transition is stronger than the call of your supposèd God - because the God you worship is powerless over you.
Everything you do to resist yourself, be it in favour of worldly desires, or of some supposèd God, is a sin. Sinners never win.
