I had a similar experience with Lord of the Flies at a sleepover as a small kid, and I know my parents cursed the best *** video (

Is your family a member of any support groups for families with LGBTQ children? However, your letter also makes me wonder if he has enough support overall. There is not quite enough information in your letter to understand precisely what you mean by "he’d be bullied anyway" because he "tends to big reactions when things go wrong," but that framing does raise some flags for me.
And this is easy enough to address, though of course there are no guarantees. We only live about five blocks apart and are in a safe, quiet neighborhood, yet they won’t even let their son walk to our house, and they never leave him at home alone. He’s 13, and it’s five blocks!
While I think a 13-year-old should by all means be allowed to stay home alone and walk five blocks on his own, I can understand, at least in theory, why these parents feel reluctant.
