That's called social pressure bias, and there are ways to curb its effet and to account for it. But anyhow, look at France (77% think it should be societally ok), where 3,6% are gay. Then you have America where 3,8% are gay, despite 60% societally okaying.
with obviously gay men, you can tell. But there are no obviously gay women, or if there are, there are less of them.
what's the point? I'm not telling it myself.

Yes.
Why is it that gayness is so much more rare in primates than humans?
