Gun laws are simple. Fewer guns = fewer gun deaths. The US is a story of rich white men who stole land to build a country using violence and oppression of anyone not a rich white man.
Since the beginning of North American colonization, rich white men have been afraid that those we are oppressing will rise up and do the same as we have done to them. That is why there is a 2nd amendment. That is the reason gun reform is so difficult in the US. Rich white male fear of reprisal. The problem is that simple. Similar to erectile dysfunction caused by a sedentary lifestyle and poor diet, it is not surprising that few talk about root causes.
