Sounds a lot like they’re hoping it’s a phase and will “work itself out”.
My oldest is NB, they’re 15. I like to think we’re about as open-minded as it gets, but I still had the thought that it might be something brought about by seeing people they look up to being a certain way and not from internal, intrinsic reasons.
I hope your daughter’s friend ends up ok. If nothing else then knowing there are people out there that think of him might help with feeling isolated and misunderstood.
