Since the only answer for you is making semi-automatic guns illegal Nosmo, there can be no compromise. That move clearly makes everyone less safe. It also makes it less likely citizens could mount a defense against the government, should that day come.
The problem with scared, ignorant people like you is, they want everything without a cost. Freedom requires, nay demands strongmen be laid low by a freedom loving population. That takes weapons. There are many countries experimenting with a gun free society. Feel free to live in what you consider freedom there.
Regardless of whether that comes to pass, criminals need to be somewaht afraid of us and our capacity to defend against them. So far, you have offered nothing of substance for your point of view. Its all isolated cases of mentally unstable people with violent tendencies and access to weapons.
Again, applying that logic to motor vehicles would ruin this country. Some play out violent movies in real life. Should we ban them? What about ending the use of medicines that helps thousands,but kills a few? You aren't getting out of this world alive. Try focusing on real threats. Your staircase is hundreds of times more likely to kill you than a gun.
Let's talk about lessons in tyranny and how it was suppressed in at least my lifetime.
If there was every tyranny in this country, it has happened over and over. The tyranny shown to the Cherokee living in the American southeast. Driving them westward on the Trail of Tears. The tyranny shown by southern slave-holders who bartered human lives like any other commodity. In both cases the issue was settled by guns.
I want to talk about the Civil Rights movement.
The Civil Rights movement was by-in-large violent even though the source of the violence was largely the authorities or armed private citizens. The Civil Rights marchers themselves were largely non-violent, preferring tactics like sit ins and boycotts. In response, the authorities turned fire hoses and tear gas on them. The Klan wasn't as benign. Eventually, and after much torment, the Civil Rights marchers won. They combatted tyranny and didn't fire a shot.
And that in my life time. Actual tyranny faced down by something other than the flash of a muzzle or the concussion of an IED.
You take a noble road combatting tyranny. But the gun isn't as indispensable as it's characterized. Not military weapons anyway.
Gun rights will be preserved as bolt action rifles, shot guns and revolvers are not on the table. High capacity magazines and semi automatic firing systems must be placed under the authority of well regulated militias, not the street.
