So you just smile and nod, but inside you think "American racism may be bad, but our racism is true and based on evidence"?
I mean, look, if you want to condemn Romani culture, sure, I can at least listen. (There are some in the US who think "all cultures are equally good"; I am not among them.) But if you want to condemn Romani because of their race or ethnicity, and say there's "some truth to the racism", then I'm going to condemn you as a racist. And to the degree that's part of your culture, I'm going to condemn your culture.
This is also why I'm very skeptical of modern progressivism. It's not like people became more aware, because they still have a set of beliefs they don't question, it's just that those beliefs changed. Which means that they might, and probably will, change again in the future. If it took 60 years to go from "racism is best" to "racism is the worst" without any fundamental change to how we create our social norms, then it's not outrageous to claim that within another 60 years we might go back to "racism is best".

And yes, that's not negotiable.
