In my life, I have seen a lot of evidence for "Mom makes 'em gay." It's like daddy issues push women towards sluttery. Mommy issues push dudes toward faggotry. I don't claim to know what it is exactly. I don't necessarily buy into the idea of smothering or whatever they say it is. Just the relationship with mom. Which, incidentally, highly overlaps with Jewish gayness. You have a ton of famously-weird Jewboy-Mom relationships where boy ends up taking it in the butt.
