The racial tension is created artificially as the left gains more and more control of the direction of the country. The SCOTUS has contributed to the racism problem by supporting the left and their PC.
They have embolden the left to tear the cover off the ball, as they feel they have politics, the courts, and the heart of the liberals, and the new century mentality.
In reality, it is because the blacks who have been here for 400 years, and have been free for almost a 150 years, and further freed since the 1960s have failed to prosper. They excel in sports and music, but they are at the bottom of academia, and white collar jobs.
While, Asian immigrants can come to the US and prosper because they are excellent students and business people.
The Blacks want to be given, while the Asians for example want to work and succeed.
My opinion will probably be called racist, but there are facts that can be found to support it. Look at the welfare rolls, look at the prison and jail population.
The students that do well in the US despite the poor performance of the US education system had to do with on their own. They had to want to succeed and they did do it.
In the 1800s the Chinese were forced to work hard labor on the railroads. And during WWII the Japanese Americans were held prisoners. Yet, you don't hear them complaining, because they are too busy succeeding in America.
Even the Vietnamese who lost their country had succeeded in the US.
So my answer to the ? is not that it is Racial Tension, as much as it is Black Tension from never progressing other than sports, and music.
Delete this for whatever reason, it won't change my opinion, or reality.
