Queer person here. I have a number of friends who are trans, some that are gender neutral, and a number of different sexual orientations.

The vibe I'm getting is not necessarily that it's trendy to be trans, but a lot of people realizing that they don't have to all be all in one camp or the other (more gender neutral). Eg, some people realizing that they can wear whatever they like without judgment. A lot of people just being more relaxed and not necessarily all blue or all pink, haha. And sure, I'm sure things will settle over the decades, but in a similar vein to the civil rights movement, women's suffrage, the gay rights movement, etc. It'll fall out of favor with the internet's eye of Sauron, and something else will be the new baby.

In other words, we aren't seeing an uptick in more queer people. What we are seeing is people who have been guarded for awhile now feeling okay to be a bit more relaxed.

And for what it's worth, a lot of people- many of my friends- aren't interested in surgical transitions. Most just wanna live their lives with a couple of social changes and are happier than they've ever been. It's kinda sweet to see someone who has always spoken in a monotone suddenly become cheerful and way brighter :)
