No, it's the "protecting the well-being of children" I'm after, as I clearly stated in my "Second.,..". Again, compare the way we treat minors with other body identity disorders. We don't promise them amputations or paralyzations if they keep up their disorder until they turn 18 in those cases. Or give the, drugs/ hormones to enforce/ stabilize their disorder. No, we treat them, we try to help them see their delusion, and help conquer it.
Now, am I saying transgenders do not exist? I most certainly am not. I do believe, however, that minors should not be allowed to make life altering decisions, for the reasons I posted earlier. And, I believe that, for minors, it is unwise to give into this, possible, delusion/ disorder, especially with life altering hormones and/ or surgery. And yes, they give life altering hormones to minors (16+ in NL). You can't vote, or drive a car, or drink, or buy cigarettes, or weed, get a tattoo or piercing, have sex, because you're considered not mature enough, and rightly so, but sure, yeah, the hormones, not a problem!
Furthermore, due to the impressionability of minors, especially primary school aged children, I do not believe it is wise to teach them about transgenderism and gender identity. And no, this does not mean I object to girls playing with Legos or boys playing with dolls. To be honest, I find it wholely plausible that for a section of children who feel/ profess to being transgender, they are inclined that way because, for instance, a girl wants to be a construction worker, a male job, by "gender norms".
And an awesome ad hominem to boot. That'll teach me!
