This is what I find so exhausting about those who try to drum up some kind of controversy around gender identity. Assuming it is all just a fad, who cares? Where's the issue when people decide to switch their gender on a whim? It's their lives. People do all kinds of things on a whim. Adults, teens and children too. Especially children, in fact. Sometimes people regret the things they did, sometimes they don't. Oh well, it's part of life.

I could understand being concerned about a social trend if it was causing violent behavior that negatively affected other people's lives, but this isn't that. Who is it hurting if someone decides to identify as another gender? Even if they pursue medical intervention, it's only going to affect them at worst. If anything the small government/pro-freedom position should be to defend the right of those people to live how they want.

The issue, at least for me, starts when we give children drugs and surgeries to enable them to switch genders.

There's nothing wrong with little Timmy wanting to play with Barbies. He doesn't need hormone injections because of it.

People are worried about their kids. People are scared and the media amplifies the most extreme voices. Establishing scientifically the effectiveness of medical interventions is difficult in the best of circumstances and most psychology is non-reproducible, so it's hard to know what to believe is best.
