Truth, thats why the most that can happen they realize what theyre doing wrong themselves and fix it (rare occurrence because of tje narcissism and how the feed off of validation and oppression)
I think he will figure it out by himself that he is delusional
he really isn't that self-obsessed
for validation I've noticed he doesn't use the trans flag anywhere so I doubt its for validation
If they have tranny friends then it's over and there's nothing you can do about it. You can hope he eventually falls out with them and at that point the path to redemption is open
