I grew up with the alternative kids in school during early 2000's to mid-2000's; the goths, punks, grunge kids, anime nerds, the freaks and geeks. These kids are more likely to be LGB, don't think any of my school friends were straight, usually bisexual. But transgender was NOT in our vocabulary. I didn't even know much about it until maybe 6-7 years ago. It's definitely been pushed hard for the past decade.
