Those are rational concerns. They really are. And these are all concerns that a physician could address when talking to their patients who might be starting to question their gender. And that’s how it should stay.
All that to say that unless you are a trained physician, or are an adult experiencing gender dysphoria, or are the parent of a child experiencing it, it’s none of your business. Trans people exist. Let them exist peacefully.
Please re-read my statement. I didn’t say you are against trans people. I simply said that these are discussions best left to a person and their physician. As a cis man, I should have as much say in the matter as I do on abortion or breast reduction or hysterectomy, which is none until it directly involves me or my immediate family.
