The root cause is the orange dictator encouraging monsters like this shooter

People in the US are under immense pressure, constantly

If people weren't dying from completely treatable diseases, if they weren't afraid of everyone in their community being armed, etc. they would less inclined to lash out at things

Of course, it'd help if there was less bullshit to lash out against too

Then there's the matter of hateful, ignorant idiots being encouraged to be violent towards the people they fear

Conservatives are filth

Root cause is something most people can’t do.

from this weekend’s murders in Minnesota to the congressional baseball practice shooting to the assassination attempt on Donald Trump.

Three totally interchangeable events with comparable motivation.
