FOR THE FOLLOWERS, ADHERENTS, PROPAGATORS AND BELIEVERS IN AND OF THE DOGMA KNOWN AS "CRITICAL RACE THEORY":
Yes, some of those who brought black slaves to America were white people. They were white people who bought the blacks from other blacks or from Arabs.
Yes, 2 - 3% of whites in the southern US owned slaves. Yes, 26% of free blacks in the southern US owned slaves and NO it wasn't due to manumission that they owned them. If it had been to take advantage of manumission their slaves would not have been listed as slaves - they would have been listed as free blacks - they were not.
In 1860 blacks had NO power to free themselves. It took a war and more than 620,000 deaths on the Union and Confederate side to bring and end to slavery in America.
In 1954 American blacks had NO power to free themselves from racial segregation and Jim crow laws in the south. It too Supreme Court rulings and intervention by Republican President Dwight Eisenhower to end school segregation and the Voting Rights Act and Civil Rights Act during the administration of Lyndon Johnson with Republican help (the segregationist Democrats in the south refused to back Johnson) to end de-facto segregation and discrimination.
So, BLM, Antifa, Democrats and other critical race theorists you are ordered to cease and desist in your efforts to pit American against American based on skin color. You don't have a leg to stand on and all of your propaganda is simply lies!
White people are not oppressors. White people are not even a majority in the world population.
STOP WITH THE BULLSHIT ALREADY!
