I highly doubt it. If that claim is put forward I'd be highly suspicious that the person in question wasn't abused in some way. A genetic study was done and the conclusion was there is no gay gene, homosexuality is the product of nurture not nature.

Depends on what you mean about "good nuclear families". I mean, much of this isn't scientific (because they won't research it), but even if there's no overt abuse, you can usually find the reason. The mostly "good" family (in social work/psychology known as "good enough" parenting), where there's two sons: one's the athlete, all-star, coordinated, etc., and one is not. Which one does dad pay more attention to, and give more esteem to? If the other one feels rejected by dad, sometimes that one ends up gay. But not always.

Yes but that contradicts his narrative so he'll dismiss the outliers. It's easier to live life with a simplified viewpoint because constantly challenging yourself is draining and disorienting.

I live in an area of California with very few blacks, to be honest, so that's hard to say. I will say that Los Angeles social services, not far from us, is a complete mess, and they of course do. Actually, something really interesting race-wise I can tell you, a fact that makes folks I tell it uncomfortable: When I was finishing my masters degree, I had an internship with county social services, the traditional "social worker" job that most people think of. As I was learning about the different abuse situations that my field supervisor encountered on the day to day, I noticed that she didn't have a single sexual abuse case on her caseload. I found that odd, and asked about it. She said that the sexual abuse cases always have to go to the Spanish-speaking social workers, because the majority are from Spanish-speaking families. Excuse me, whaaaat? Haha, that was a 🤯 moment for this young social worker. All the stats that are unfit to print!
