Has it occurred to you it's entirely possible that some people at typelevel are black? And you're saying that yes, they
should interact with and condone the views of someone that would see them enslaved and feels they are inherently inferior and should have fewer rights than him?
Maybe you could. Maybe, if someone had consistently argued that you and your family were of an inferior race and should bow to their will as is your ordained place in the universe, you could shrug it off and say, "let's agree to disagree and get on with things".
I'd guess this has never happened to you though. I'd guess you can have this position because this is not your safety and your rights that are in danger. It's always so much easier to consider hatred acceptable when you're not its target.
