I completely agree with your post.  If you spend anytime perusing these boards you can see a pattern.  There are the regulars agitators I see time and time again....I guess "snark" and RadirR or whatever and their ilk mentioned above are permanently assigned to the Denver Post.  Yet time and again I will see a poster pop up once or twice only to slink into away after the most vile and hateful comments I could never see one American express about another.  

If the goal of Putin's Russia was tear apart from inside it is certainly working.  I am not naive though, I know many Americans are capable of such hateful sentiments and they are being used as tools.
