The fact that it was legal to have slaves of one race in the US but not another is an indication it was motivated in part by racism in the US.
Both your arguments suffer from the same failure to understand enabling factors from primary motivating causes, so I give them the same response (again).
Something being "a factor" in allowing something to happen doesn't make it the primary motive people have for making it happen, which is what I actually said. I never implied that racism didn't exist or play a role. I said the desire to maintain slavery in 1860 was not primarily based in racist sentiments.
If you want to marry a woman and her father's approval (which she cares deeply about) allows that to happen, does that make her father's approval the primary basis for your desire to marry her? This is the "logic" you are applying. Did the slave owners pay slavers to go to Africa and get slaves primarily because they hated black people and just wanted to bring them to the US to make their lives miserable? That is the absurdity that you presume by claiming that slavery was primarily about racism.
They paid to get slaves in order to profit off of them. Cultural racism merely determined who were the easier victims on whom they could profit via this method.
