IMO, your opinion is right on target. I've known a number of gays over the years, and NONE of them were mentally normal (and not just the "gayness" issue, they were unbalance in other ways, too). Some were VERY bright--but still nutso.
“...Some were VERY bright—but still nutso...”
That’s been my experience.
True story:
A former co-worker of mine was named Gay. One morning while making my rounds, the nurse manager was orienting a new hire RN.
My friend introduced herself, “Hi, I’m Gay.”
The new nurse’s eyes brighten and she beamed, “Really!? Me too!”
