> I'm not saying everyone is born a potential mass murderer
That's exactly what you are saying.
> only that you should need a license to own a gun
> you need to subject yourself to deep government scrutiny
The USA was founded upon some very simple principles. Everyone is innocent until proven guilty. You have the right to bear arms. You won't be subjected to unwarranted government interference.
What you're advocating for violates all of those. You don't see free human beings whose innocence and right to be armed is presumed. You see suspects, potential mass shooters who have no business owning firearms until they prove to the government that they're innocent.
The right to bear arms is a symbol of a people's freedom and self-determination. You'd see them reduced to sheep in exchange for the illusion of safety.
> The fact that you inferred "everyone is born a mass murderer" from that says a lot about how sick America is compared to the rest of the world on the matter of guns.
I'm not american, I'm brazilian. I'm part of "the rest of the world".
Brazil is a country that actually held a referendum about gun control, discovered that over 60% of the population was against it and then effectively disarmed us all anyway. As a result, armed criminals invade our homes with the absolute certainty that we pose no threat to them. Even in formerly peaceful rural cities where some of my relatives live.
I suggest you think very carefully about what sort of future you want.
