Are people who cite the 2nd Amendment honestly familiar with what it establishes?

I cannot speak for everyone who cites the Second Amendment, but I can speak for myself.

After I retired, I didn't feel the need to immediately acquire my own firearm and was more focused on transitioning and making the most of my civilian life. In 2021, I was living in Nashville, when protestors set fire to the Capitol building. The civil unrest gave me an uncomfortable feeling and I realized I was not equipped to protect my family. It was then that I decided I wanted a firearm. I spent six months or more researching firearms, ammo and laws relating to carrying a firearm in public. I had some missteps at work and was investigated related to owning a firearm. Twice I was asked questions during the investigation and already knew the law that answered the question, because I had already done my homework and I had acted legally. I did have to look up the number of the law in the Tennessee code so the investigator could verify the information I gave them.

Now, my question for you, is are you honestly familiar with a what the 2A establishes?!?

Can you fly an American flag in the UK in your own private property there? What is the UK’s government stance on that? And if yes, do you also have to fly the UK flag or the American flag can fly solo?

I grew up around firearms, when they were left on racks in pickups and displayed in wood and glass cabinets, much like a China cabinet. After high school, I joined the Navy and while I wasn't around firearms everyday, I was around plenty of firearms and have fired more different firearms than most in the military.

All that to say, when I say I have studied the Second Amendment, what it says and what it means, I put as much time and effort into knowing the 2A, as I did Tennessee law and which firearm I chose for my first and why. I am intimately familiar with what the 2A established.
