It’s disappointing to see you pull out such an easy, cheap, and tired stereotype.

So there are no gay flight attendants? There isn't an overrepresentation of gay people within flight service?

I didn't say all flight attendants are gay – this is obviously not the case. But some are, and I've met quite a few of them. And if I try to average out their voice and mannerisms in my mind, it leads me to a sonic place that's close to this voice.

We’re not talking about the same thing. There are likely gay people in nearly every occupation. That you think you can tell by their voice is ignorant and prejudicial.

One probably can’t tell that with 100% precision, but the brain is a fantastic statistical prediction device that is specifically wired to make deep inferences from vocal patterns. I would imagine the correlation between “gay” vocal characteristics and actual homosexuality is close to 1.
