First off, it isn't race but nationality.

And what I said, not very well, was an attempt to navigate the very legitimate idea that what people think regarding what is racist can be a sign that they themselves are inadvertently engaging in racism. Here's an example, there was a story of a white guy who brought a watermelon to a company party with a lot of black guys. He then got fired for being racist. Regardless of the details of this actual event, in a hypothetically similar event, if his intent is not known and somebody thinks that what he did is wrong because "these poor black guys must have been offended by the party watermelon," that person begins to enter territory of his own racism.

This kind of racism is real yet goes wholly unaddressed by many. It's where we get total nonsense of explicitly racist ideas (like affirmative action) defended as anti-racism. What seems to truly be going on is the "white savior complex" element of racism. "Oh those poor blacks can't achieve success on their own, we wonderful whites need to pass laws that benefit them exclusively....."
