I’m Latin American, I’ve seen some people use Latinx here, but I personally prefer Latine because it rolls off the tongue much easier. Ideally though, I’d personally rather be called Latin American to avoid the pronoun altogether. Again, though, that’s a personal preference of mine - in languages with gendered pronouns, I personally prefer avoiding using pronouns toward myself altogether as much as possible.
At least in my experience, it’s not really uniformly decided and also became a Culture War thing in here as well.
It’s moreso that they think “by the time shit hits the fan, I’ll be long dead anyway, so I don’t see why I should care”. Ergo, pure, distilled lack of empathy, a “fuck you, I got mine” aimed at the future of every living being in our planet.
