As others have noted, I don’t think you can bait any relevant information from them. And this works both ways: some people are okay with homosexuality (or whatever) in the abstract but “don’t think it could happen to them,” if you catch my meaning; other people, love for their relatives overcomes homophobia.

Incidentally, this was part of why Pride became what it is: since it’s easier to hate Someone Else than your own family, coming out en masse forces people to confront homosexuality as a tangible rather than abstract thing, in the context of people they love.

I don’t have any particular advice for you. I can only say that I don’t regret having come out.
