It doesn't say you get any firearm
It says shall not be infringed which means what it says. There is no prescription for what is allowed but instead the opposite. The government cannot and should not prevent the population from arming itself. If people think that's disagreeable then they should amend the constitution not defy it.
The constitution was written by people who had just overthrown a government. This amendment wasn't written to protect the rights of hunters. It's specifically to enable the people to take control if the government gets out hand.
Also, which militia are you a member of, specifically?
Do you think the US would allow a militia to exist when it's entire purpose is to be a check on government power?
No I haven't. Sorry but kids don't get to do whatever they want precisely because they might kill themselves or engage in self harm. That's a symptom of something else. I suspect it's lack if a structured home life, unmonitored internet access, pornography and the hypersexualized culture at large among other things.
Minors (especially teenagers) will do anything for attention and being 'trans' is often a means to that end. Even worse it's often presented as a solution for problems it can't solve. Parents can fall into this trap too.
Yeah there's nothing permanent about stunting a childs adolescence while everyone around them naturally grows into their bodies and actually learns what it's like to be a man and a woman instead of weirdly speculating on the sidelines. We're robbing kids of normal childhoods by not just allowing but often encouraging them to obsess over this stuff.
Kids should have hobbies, read books, be responsible for chores at home and be raised by parents not the state. Adults can do what they want but they need to leave kids out of it.
Self-harm and suicide statistics are cited repeatedly as perhaps THE primary argument for the child trans stuff as if it is that cut and dry. It's not. I can guarantee these situations are way more complex than anyone wants to admit. Something like 1 out of every 2 or 3 adults are on antidepressants in the west. It's not because they are transgender it's because we have a nihilistic culture that offers no meaning to life outside of consumption and worship of self.
