@freemo I'm curious about that too. I think I know what you mean by "way of speaking" and it happens across many languages and cultures. I wouldn't say it's intentional or a group thing for the most part. Many of us have the same gay "accent" since childhood and in small towns before any contact with other gays and mainstream gay culture. But of course some gay communities have embraced it and maybe enhanced it as an identity marker that may or may not be adopted.
