Yeah, well, communities that are allowed to police who is and who isn't allowed in them tend to be more tight knit and fun than the ones forced to take anyone. Maybe the problem is that you have to be "discriminated against" to be allowed to even have a community.Complaining about losing their specialness is stupid, but I'm sympathetic to the loss they feel because their communities are disappearing. I was sort of a hanger-on to the gay community in the '90s because my sister is bisexual, and the community was tight knit and ridiculously fun to be a part of.
Also, the LGB isn't just losing their community because of greater acceptance by normies. They're also getting pushed out of their own events and organizations by trans people and special snowflake straights. That has to suck.
Also, some of the LGB community is just weird sex stuff, and was only tied together with the gay rights people out of necessity. People who just want to take drugs in a club and have lots of sex (not that there's anything wrong with that!) aren't the same as the people organizing fundraisers and parades. It's natural that after the outside pressure on them fades away they'd drift apart.
