Let's try to look at this from a different perspective:

We must agree that almost all parents would have the best interest of their child on their minds. Obviously, we can't say the same about the government or the politicians who make these rules. As you can see, most politicians these days are total nuts and lunatics.

Each kid is different, and trying to fit one rule to all isn't the best for the kid. No parent, no matter their political affiliations, will try to change the gender of their child for purely political reasons. Some trans kids already show an affinity toward a certain gender identity, and not being able to associate or assimilate can physiologically scar them for life.

Now, the question for you: Would you trust your parents to make the best decision on your behalf or the political hacks who would do anything to remain in power and force their agendas on you? The choice can't be clearer.
