That’s an interesting take. Declaring one’s pronouns as a way to announce one’s presence (or not) in a dating pool. Okay, but personally I doubt that’s the main driver. After all, in the internet era, finding one’s tribe is as easy as two taps on a screen. Gay guys can now have as much sex as they want without any third party even knowing, as you must be aware. I certainly am, indeed I speak from experience. So this phenomenon of needing to wear jargon and pronouns on one’s sleeve, I think it has other causes, mainly.
