Actually, I am not. Slavery was a global institution at the time. It is true the vast majority of slaveholders in the US during the 1800s were white, but they are dwarfed in numbers by the number of slave owners in Africa and other parts of the world. And in fact, the white slaveholders acquired the original slaves from African slave owners. So were these original African slave owners in Africa "white supremacists"? Does someone who purchases slaves from an African do so for racial reasons or economic ones?

As for my ancestors they were not in America at any time during the period slaves were owned, nor based on our ancestry did any own slaves for at least the 800 years, we can trace them back. On the other hand, Barrack Obama's parents included an African man and a white woman, the latter descended from slaveowners.

If they had not come to African seeking slaves, those slaves would have sold to Arab slave traders that secured their slaves and sold them into the middle eastern and north African slave markets.

Alternatively, they would have been executed. As tribal groups fought each other for control of land and the last thing you want to do is leave your enemies alive to seek revenge.

Finally, even after England and the US teamed up by putting their navies off the coast to end the slave trade, it remained lucrative enough that slavers continued to try to evade their blockades and sell the slaves. When navy ships pursued slavers, they often slit the throats of the slaves or scuddled their ships to avoid being caught.

Again, slavery was a horrible institution. And as you know the word "slave" refers to white slaves. In the past, so many "slavic" white slaves were taken, that the word become synonymous with the institution.

Meanwhile, hundreds of thousands of white people perished trying to end slavery. So again, the institution is horrible and trying to equate it with white supremacy is simply silly and ignorant.
