As a rule of thumb people stop to mass murder other people, without guns. With extremely rare exceptions, we don’t have that shit outside of the US and our schools are not shooting ranges.
The other two things you wrote are not reasons, they are a) a slogan that you could put on a 12 years old t shirt and b) something someone who is having a heart attack might say
Outside the US sure, that was my point.
In the States there’s a mass shooting every Tuesday.
