This is the point.
It doesn't matter that someone uses paintball for self defense. Government will come after you if you use a baseball bat for self defense. Government will come after you if you use a 2 by 4 for self defense. They will come after you if you use a fork and a dinner plate. They will come after you if you use your fists. The thing that they want is, FOR YOU TO BE DEFENSELESS.
Oh sure. They may go after the person who is assaulting you. But they will come after you too... for defending yourself. They want you defenseless.
For example. Let's say that I have 3 acres of land. And on this land I have 15 military tanks that I own, all of them armed and fueled for war. And ad to this all kinds of arms and ammo, bazookas, grenade launchers with their grenades, rocket launchers and rockets, ack-ack anti-aircraft artillery, and you-name-it, all armed and ready for use.
Let's also say that the land is well protected by razor wire fencing and perimeter security cameras that don't allow anybody in to steal any of it. On top of that, I am the sweetest, most innocent of all people who wouldn't hurt a flea.
If government found out about my stuff, they would be in there in a minute to not only steal it from me, but to charge me with something, as well. And if they couldn't get in, they would come with more and bigger artillery to break through my security.
The point is, the people who we call government, want to keep us defenseless, and if they can't do it, they will USE all their weapons on us to keep us defenseless. So, who are the dangerous people? It's the ones in government who use their weaponry for whatever they want. And more often than not, they use it against those of us who are defenseless.
Government is violent. We need to take their weapons away from them before they hurt us.
