Other countries have "freedoms" like the states. Finland has very less restrictive gunlaws like the US except they have common sense background and mental health checks.
The 2nd amendment was never written with these kinds of firearms in mind, What does "arms" even mean in the modern sense? Can you own a tank? How about an APC? A cruise missle? This was all written with muskets and carbines at best.
Back then, there was an actual threat of retaliation by the British. Nowadays, Tyrannical government is just a term thrown around by NRA higher ups to help sell guns through fear so they can pocket some cash themselves through donations. Nothing more and nothing less, The US won't change because it is a country that is founded upon fear. I don't mean it as an insult but its what it is, I love my American friends and family and I hope all the best, but for that, you need common sense gun laws.
