I think it is an offshoot of the lgbt success of using militant and political power to mandate that the majority conforms to the whims of the minority.
They saw how successful was the lgbt in claiming equality, and how weak was the constitution.
Now, the blacks that have made zero progress on their own, want to once again blame the whites, and the majority for their inability to to what other late comer immigrants have done.
Asians coming into this country even starting back at the Vietnam War when the US took hundreds of thousands of them into the country, have assimilated very well and quietly into American. Like the rest of the Asians they embrace education and technology and found their place in the American workplace.
They don't populate the welfare rolls that Blacks have been on for decades.
They also don't populate the jails and prisons that are populated by the blacks. There are two million people in the US jails and prisons. And a large number of them are black.
With a two term black president, and two black US AG, you would think that would inspire the black community. In Los Angeles more blacks are in gangs than college.
Blacks excel in sports and music, but those that aren't in those field don't excel at anything productive. They do well as criminals but not as productive citizens.
The Chinese were forced into indentured servitude in the 1800s to work on the railroads. The Japanese Americans were interred during WWII, and the European immigrants in the early 1900s were given nothing but entry into the country. Yet, all of these people did well, while Blacks haven't done well. And today, it seems like they shot backwards 50 years.
Killing cops should be deemed acts of terrorism!
The good black people need to lead the bad black people back into America. President Obama has an opportunity to lead them also, but he has failed to even try to date.
