Barack Obama and the left have used their divisive political correctness agenda not only to attack and infuriate their opponents, they have used it to inflame and enrage their own supporters, who they knowingly and intentionally have tried to pit against each other.
At the same time they regard and promote their "Political Correctness" agenda as more important than literally anything, including our national security, law and order, the US constitution, civility and national unity, etc. This agenda has been extremely harmful to our country and the people in it are angry to the point where systematic violence is becoming a real concern.
In fact, some people are quite concerned about the possibility of significant violence after the election, perhaps regardless of who wins. That appears to be a very legitimate concern, especially when you take into account the violence and lawlessness we have seen in places like Baltimore, where the Democrats in charge of that city effectively tied the hands of the police and stood by while rioters looted and burned that city.
These are very frightening images to any sane person. Of course, this was not the only incident of rioting, looting or criminal violence that we have see take place over the last eight years by any means. However, it should be noted that in nearly every case, these acts of criminal violence have been conducted by supporters of the Democrat left. I would not put any bets on it staying that way for very much longer.
The rage and hostility that we see engulfing our country right now has been carefully cultivated and nurtured by Obama and the left, because they believe this is an effective way for them to empower themselves - at the expense of the American people. He and his associates thought it would be good to really aggravate the fire out of pretty much everyone. Well, they have achieved their objective, perhaps too well, and our nation is much to the worse because of it.
Barack Obama is the most effective enemy our country has ever faced, hands-down, case-closed, game-over. He really is.
