The younger generation(s) seem less uptight about the possibility of being perceived as gay, so they feel free to express themselves in ways that (30 years ago) used to be construed as telegraphing that.
That said, the younger generation(s) also seem to be a lot less worried about whether they *are* gay, straight, or bi (or whatever else) than people who are now in their 40s and 50s. And that's a *good* thing.
My take on it is - and I've been saying this for decades to anyone who will listen - "gay" is just a label, and not a very useful one at that, for people who have sex with other people of the same gender. And already we're in trouble with that - does it mean "only" or "always", or just "sometimes"? Which gender is "the same" if one or the other is trans? Or cross-dressing? Or non-binary? I could go on and on... but the bottom line is there are over 7 billion human beings on this planet, and no two have exactly the same sexuality. So what's the point of putting them in boxes?
If anyone wants further evidence for my theory, I can give chapter and verse of my own story, which has quite a few adventures that demonstrate the point.
