When are people going to realize that this American government actively gets off on harming and killing people?
They do realize this. They approve of it.
Conservatives generally operate from a circle-of-concern perspective. The people who matter are their immediate relatives, friends, neighbors, and coworkers. The topics that matter are those that directly affect them right now. Everything else is unimportant and ought to be stopped or, preferably, destroyed, so it doesn't take anything whatsoever from "me and mine", whether that's something I currently possess, or something I will or would like to possess.
And anyone who opposes this perspective on reality is an enemy, and a part of the stopped/destroyed -- personally and in everything they care for or about.
