Why ??? Why does this happen in the US ??

At least 6 people were killed in a shooting at a Walmart in Virginia, officials say. The shooter is also dead.

I think there are few very understandable reasons that the US has more and more of these mass shooting events.... 

#1 - Obvious - we have more people that own guns,,, and more guns are available to anyone and everyone... Come on ,, how can this not be  factor... 

#2 - More and more lately the political rhetoric has radicalized these lone wolf type assailants. The more hate talk - the more that one side demonizes the other them more you are gonna have someone that thinks that killing others will solve what they see as "the Problem" ...   IMHO - we are not far away from an assassination of a Politician... Senator,  Representative.  Judge,,, someone is going to get killed,,   these people these days have guards following them and their families around...  think of that ,, seems like something that you hear about in a 3rd world country ... Not in the US.... But since the former POTUS got into the game - he has worked to Demonize his opponents -  he has used hate speak to do it... and he and the followers  in his Cult are at least part responsible for this .....   

Today more than ever - you cannot have a discussion of politics,,,  there is no more compromise in the system, its MY Way or nothing,,,  YOU are not allowed  different opinion....  and I think that mush of that is driven by the fact that we are not both dealing from a position of Truth, FACTS.... actual Truth - not Trump Truth (Lies) ......
