There are many factors that contribute to a loser deciding to become an evil loser and shoot up a bunch of innocent (or even random guilty) people.
However, the statist knee-jerk reaction to enslave us all with “laws” for the acts of a few is just as bad as shooting into a crowd of innocent people. It absolutely is.
“Laws” kill people, including innocent people. That fact is swept under the rug by those who want to impose “laws”. All “laws” are enforced by death, no matter how trivial, but that’s not the only way they kill people.
If you are prevented from having the proper tools for defense when you need them, people may well die. Many already have.
If you advocate “laws” you are no better than those who gear up and go into a crowd and start shooting. Yes, some “laws” are less horrible than others– those are the unnecessary “laws”. But the very idea of– the superstitious belief in– “laws” is toxic to society. Don’t go down that path. You can be better than the evil losers. Act like it.
