Most of these children who are involved are merely just kids who choose to partake in things that are not the realm of their outward gender (so, for example, girls who don't like "girly" things, or boys who don't like doing boys activities). That doesn't warrant mutilating your genitals and permanently destroying any chance to have children. And if children are too young to consent to sex or even learn about it, then they are too young to make life changing decisions and take dangerous, irreversible drugs. A transgender child is like a vegan cat. We all know who’s really making the decisions. Also, what happens if they regret this decision later in life? There is a reason why the age of consent exists, you know. You don't support lowering the age of consent, do you?
