Try, if you can, to provide an example of genocide that wasn't preceded by mass-disarmament of the targeted populace (assuming they hadn't been previously disarmed).
What jail sentences for terrorism offences did they recieve? Or were they shot by police? Or were they white people?
(In other countries, you can't just show up to political protests with weapons!)
I think you know the answer to that. The answer is kind of my point, isn't it?
These people are dangerous to push around because they have guns. They realize this. They are not going to relinquish that leverage without a fight.
This works until a politically opposing group shows up with guns as well.
Would you argue that the group most subject to being pushed around by the state in the US - young black men - would be better off arming themselves?
Remember what happened when the Federal government tried to get some farmer to pay for the grazing land he was using? People several states away showed up with rifles, and they had no skin in the matter. If you tried to take their rifles, they (and many others) would try their best to kill you.
If America were full of Europeans, perhaps it would work. It isn't, so any notion of gun banning in the US is nothing more than wishful thinking at best.
