Well, Phart, hear this. As Bella pointed out in her other thread, there's this pesky document know as The Constitution of the United States. In it there are several freedoms that are guaranteed to all. One of these says (I'm paraphrasing), "● Freedom of speech: Free speech is necessary for the discovery of truth and the rejection of falsehood."
This allowed people to say or put down in writing whatever they fee they want to say without fear of being incarcerated.
The best law enforcement can do is monitor the individual and that is only slightly better than trying to stop the ocean tides.
Another freedom is the right to bear arms. No one remembers that the second part to that freedom is, "in order to maintain a well regulated militia".
You put these two "freedoms" together and that's how these tragedies come about.
Now, no one is naive enough to believe that these tragedies can be fully stopped. I don't think so either, but, regulation of firearms can certainly reduce the amount of casualties and/or number of such calamities. Even you have to admit that you can kil.l more children with a high capacity semiautomatic rifle than with a regular weapon.

BOTTOM LINE, unless we become an authoritarian country where freedoms don't exist, or we need to regulate the TOOLS of all this kill,ling.

You have shown signals of it several times, fantasizing about an armed rebellion, when Democrats win the election. You have also told stories about you protecting your hill against whoever comes for you, which is a fantasy, because no one comes for you. You are content with your life now, but if
you lose everything, I see your fantasies of gun violence becoming a risk.
You're already angry about everything, that combined with sorrow and desperation is a toxic mix. It happens every day in your country.
It's not just the availability of guns, it's also your media.

Your media keeping their viewers fixed to the screen with constant fearmongering, creating outrage and anger. It fills people with bottled up anger, directed at a few scapegoats. Both sides do it, but the right-wing does it the most. They take everything that happens to and create a story with the intent to strengthen your bias towards their narrative and against the enemy, because it binds their viewers. They cannot go a minute without attacking the Democrats, liberals, unemployed 'moochers', working people in general, teachers, immigrants, black people, transgenders or wokeness in general.
You cannot watch that without it affecting your brain and stress. As long as
you personally are fine, you can suppress it, but it comes out when you are desperate. Then you will just be another statistic. Some of your acquaintances will say that you were a nice hard working guy, others will say they were afraid of you going mental, because of your big gun collection and extremist ideology.
Did you ever listen to people describing a mass shooter?
Many of them were just like you, but just snapped one day.
That snapping doesn't happen without build-up tension.
No entity builds up tension as much as right-wing media.
They are stirring in a pot of hate, adding ingredients, 24/7.
And just like phart and tecsan, you eat out of that pot as much as you can.

There is a reason for why mass murders happen so much more in your country. It's not the things that are exactly the same in other countries.
We have crazy people too. We don't have your guns and we don't have
your media. If it's not those things, then what is it?
