The people that became LGBTQ as a phase or fad are aging out of the demographic, and the younger kids just were never into it.
I think the younger people know it is all a scam, since everyone is now claiming to be gay to get attention or special treatment.
One place you see it is in fast food restaurants. Basically everyone working in there is gay or transgendered now because under our local law you have to give them preference before any other groups.
