OK, let's pretend the creator of "Blacks for Trump" has a crazy past and the has over-the-top ideas about Obama and Hilliary* attributed to him by that 2016 article about a Trump rally in Florida. He really might, for all I know and care. What does that have to do with the off-the-Democrat-Plantation black supporters of Trump at a rally in Phoenix, AZ almost a year later? In 2016 DJT got about 12% of blacks' votes. Antifa-BAMN-BLM antics and @#$% like this are likely to boost, rather than diminish, that percentage in 2020.
It's been bizarre, the past 2 decades or so, to watch as the goals of MLK and other leaders of the 1960s Civil Rights movement turned on their heads:
* Many blacks are demanding segregated areas;
* Many blacks are rejecting full participation in American society and culture;
* Many blacks - as well as white Democrats - are treating blacks as lock-step stereotypes.
