It's called "grooming".Instead if parsing words and nitpicking I dont think its the fact thst a child can acknowledge an attraction to a certain sex at an early age, it's the fact that an 8 year old second grader is identifying himself with a sexual identity term that most of us gen X'ers never heard of until our teen years. Or we used the slang words having heard them elsewhere without even knowing what they truly meant.
I had a crush on a blond hair blue eyed boy in kindergarten. I was very sad that he moved away the summer before first grade.
So though I may have 'identified' as hetero I never would have used adult words to define myself.
8 is too young to be labeled and it's the adults doing it.
You Nazi's would know all about that.
