What a stupid thing to say. Obviously there are mental health issues, Something is wrong in the people who perform mass killings, Perhaps that is what you call sin. Either way, we are not going to solve all mental problems any time soon. The next best step would be to limit the access to weapons of war for people with mental problems. The weapon of choice for mass killings is always a weapon that was designed specifically to kill people. The blood of the next batch of victims is on the hands of religious nuts/gun nuts, and you should be ashamed.
I strongly disagree.
The genie out of the bottle is technology.
Guns are a minor part of it.
If someone has mental health issues, they are more dangerous with flammables, toxins, explosives, or even vehicles than they are with guns.
Guns make so much noise that they get caught right away.
These other things not only can kill many more at once, but you can keep doing it over and over.
Ted Kaczynski was sending mail bombs for decades before finally caught.
The solution MUST be free health care that picks up on mental health problems early.
Nor are those with mental health issue the main problem we face.
The worst threat of all is the slow decay of the republic into a dictatorship.
Which likely is already way past the time when we should have had another rebellion, and started over.
By 1890, the wealthy elite had taken over and all the politicians are lying to us all the time.
No decent person would even run for office any more.
