Race relations were better before Obama and worse after Obama.
But that doesn't mean everything was hunky dory before Obama. That's what they miss.
Republicans "prefer a negative peace which is the absence of tension over a positive peace which is the presence of justice." Letter from Birmingham Jail.
They are more devoted to order than justice.
Therefore they pine for the days when Black Lives Matter didn't exist, when NFL players weren't challenging their mental ordering of the universe every Sunday.
There was not true justice in the 1980s 1990s or 2000s. Black people have always gotten the short end of the stick. They don't have the same wealth and opportunity as White people. That's a result of redlining and housing policy that went against them until 40 years ago, plus racism and discrimination.
Great write-up here. Not sure about the rest of your post, but this part is on point. ---
