I actually don’t disagree with some of your points.
I acknowledge (if fact, I would shout it from the 50 yard line of the Superbowl) that the media presents an unrealistic ideal of human beauty with advertising, movies, etc. that portray–for example–an unrealistic standard of thinness.
As an example, the supermodel Kate Moss popularized a fashion esthetic called “heroin chic” which emphesized an almost guant appearence that bordered on being almost skeletal.
Long before Kate Moss, there was a model named “Twiggy” who capitalized on a similar appearence of unrealistic thinness, and there were legions of teenage girls who starved themselves to death by anorexia, and more legions of teenage girls (and young women) whom were fat-shamed into developing eating disorders because they may have had just a few extra pounds . . . and I–as a straight man–don’t personally understand the appeal, because a young woman with a few curves can be very, very sexy.
I also believe that this fashion trend contributed to drug addiction because young girls “had” to start taking dangerous diet pills in order to reach an unrealistic standard of beauty, and became hooked.
So, if your concerns about kids are that they might hurt their bodies in order to follow a fashion trend in a self-destructive manner like the trends started by Kate Moss and Twiggy, then I understand your concerns and I actually respect that you wish the public to consider these issues in this context.
Still, there is a false equivalence here.
Transgender people are counseled, examined by specialists who work in this area, and a proper specialist has conceptual tools that help distinguish someone who is actually transgender vs. someone who “just wants to fit in.” Someone who “just wants to fit in” would be identified just like how a court-appointed psychiatrist can identify if someone is faking mental illness to escape criminal prosecution.
The only social agenda is acceptance of such people so that they can contribute and enjoy life on a level playing field . . . which is different from trying to make everyone trans.
If you want to look at this in another way, the civil rights movement wasn’t about making white people black. It was–in theory–about having a level playing field.
