I think a lot of what they do is talk with clenched teeth which produces something that’s almost like a lisp but not quite. Not uncommon for women to do this as well. For a common reference point listen to Mary Matalin. She does this. Course it doesn’t sound gay when a woman does it LOL.
Why do they talk that way? It’s a tribal thing. There are tons of sub-cultures that talk a certain way and gay is only one among many IMHO. Try -
- Airplane pilots (they’ve all got that Chuck Yeager thing going on).
- Football announcers (Keith Jackson?)
- Anyone having anything to do with Nascar.
- Radio Announcers - different sounds depending on the format. For NPR btw see above - the males all sound gay to me.
- Blacks
- etc. etc. etc.
I think you're right. There's definitely something to that.
