All races at one time have been slaves. This is true. This is known. And no one is better than another. Many things of holding others back are strictly political.
One race have had it better. And blinded by fiction than facts and do get upset when you point out this.
Of course when police officers do wrong? They offer their support in high manners. Justice has been more kinder tto them.
And the race that gets killed the most by them? Isn't seen as being treated harshly? Even when confronted with evidence. Notice some of majority-white juries verdicts.
Society has been kinder to them.
Take the wealthy within society. If never been poor they more likely not know of the sacrifices on many.
They barely around the poor unless it the maid/butler or hard working-class employees. But they keep pushing your dreams to be a success.
But going from poor to wealthy leaves you with a better message.
