Wow, three trans kids. Oh, no, the world is falling apart. However shall we cope. Listen, I’m usually patient with you, but you are seriously overreacting.
And no, being trans is not a mental illness. What IS an illness is gender dysphoria, which should absolutely be treated. Listen, we both know that, quite frankly, kids aren’t all that bright, but they know more than we give them credit for, especially about themselves. And before you start overreacting with “but what if they’re wrong?” Then take solace in the fact that no irreversible procedures or treatments are done to people under 18. That is, no amount that suggests it’s regular practice.
And yes, I do know all those school board meetings where parents shriek about CRT and LGBTQ+ education. Those fears are largely unfounded. Heck, CRT (I mean actual Critical Race Theory and not the umbrella term invented by the GOP) is only taught in Law School. If what you say happened to your granddaughter really did happen the way you said it did, I’m sorry she felt that way, and she shouldn’t have been put in that situation. But if you’re telling the truth, know that was a vast exception to the rule. Again, I’m not condoning the alleged action, just saying it only happens very rarely.
