I agree 100%. I have two middle school-age kids, only one of whom has entered puberty but both have extensive thoughts on what LGBT(+) means. I do a lot of smiling and nodding, and just listening, because they really see it quite differently than any adult I have met. It's very much become an entire culture that is only loosely related to actual sexuality.

I am very interested to see how it plays out with my kids as they mature, and as their cohort matures into adulthood. It's fascinating, a little overwhelming perhaps, but not particularly threatening. They aren't at all militant, and I don't know if that's an age thing, or if the culture is evolving away from it.
