Sorry Bret, but I take issue with your comment. Somewhere in middle school, we all learned about the single bloodiest American war... the Civil War, where we frickin' fought each other, brother against brother, father against son, often killing with GD bayonets. So to portray the current event/s as somehow deteriorating from a prior, higher, morally righteous societal position, I find it to be disengenuous. You live in a country that, I'll go out on a limb here, prides itself on political violence; your kids will live in that country, and your grandkids will live in that country. This isn't a one-off. We've literally had a steady stream of political violence for our entire existence as a country, often significantly worse that what we're seeing now. Does that make it right? Of course not. It's still a terrible act. But it's not new, it's the norm, and it's not going to go away.
And the reason I take a public stance against it is that any comments, from the media or others, that portray these tragedies as some form of societal decay from a previous "better" position, by default, alludes to a "new" or "worsening" problem, that then 100% feeds back into the hatred that we've been conditioned to have based on our perception of the problem. You can clearly see this on both sides, acting as a positive feedback loop of discontent and hatred.
