The easy post would be to point out that "racists once made that argument" is basically a slightly cloaked ad hominem attack trying to accuse your opponent of racism, without doing it clearly in a way that could be denied. But the more interesting post is to point out that if you allow racists the power to destroy an entire line of argumentation for all purposes forever by using it, you are ceding to them enormous power to control the discourse, even accidentally, by completely determining the bounds of acceptable debate. Racism is bad, but the way we treat it as radioactive waste nowadays has itself become a danger to society. It's merely bad. It is not the One True Sin, it is not the cause of all life's problems, it is not the One Temptation in life that if resisted means we can stop worrying about our moral status, it is not something that permanently twists everything it touches into an eternerally-unredeemable black goo, even ye unto a dozen generations. It's merely a bad thing that hurts people. Giving it the power to be those other things is an error too. So, yes, it is perfectly valid to address the question of "incompatible cultures and values". Of course, it does require one to admit that cultures have values that can differ from one another, which is, admittedly, a door that once you walk through does suddenly make a lot of the prepackaged really "nice" answers in current discourse suddenly obviously too oversimplified to be useful for any purpose, but such is reality. |
