Of course they're being manipulated. To some extent, we all are. Hitler tapped into resentment and other unfortunate aspects of human behavior and road it to power, with the deaths of millions as a consequence. If society kept telling you that every bad thing that happens to you is because of another group that dislikes you and is trying to hold you back and stacking the deck against you, there's a good chance you would resent that group, distrust them, and potentially want ‘payback’. That's unfortunately part of human nature.
There's a higher order effect than that. As always, follow the money. So let's go through a simple thought exercise:
1. Avg IQ of blacks is 85
2. Ergo, the avg base of blacks will never assimilate - they simply do not possess the basic cognitive ability to either speak, write or act according the the basic norms of society at large
3. As a result, they occupy the lowest order on the economic ladder
4. As illegal immigration and MENA refugees pour into the country, blacks continue to be pushed further down the social strata, to the point where they are isolated among themselves to percolate over perceived injustices
5. US (shadow) domestic policy is to dilute/displace the overall existing racial make-up overall. Stressors among all classes result in acts of violence between both law enforcement and those feeling the brunt of changing demographics.
6. Political websites like FR allow people who have to control to vent into the ether, whereas the smart money gives not one wit about the impact. Rather, it's quite trivial to see the action in play and hedge accordingly.
7. The uni-party is composed of smart players - they helped craft the policies under direction of their bosses - so it's almost like insider trading for them.
8. People are going to make a (financial) "killing" off of these events as they continue to escalate and create social disruption.
9. You can be a dope and complain, or be smart and play. Your choice - but as always, it's best to follow the money.
