Yes. It Is.

Florida looting crackdown is 'white supremacy,' claims author Sarah Jaffe

For this to be the case we must assume that the looters are not white and that their culture is not white culture. If that is the case, then we might also safely assume that the looters are black and that their culture allows theft, even theft by force.

So white supremacy could well be a valid proposition, then, right?

Since all cultures are dictated to be absolutely equal, then theft, being a cultural standard for some, is to be celebrated and nurtured. White culture is to be rejected, because not to steal would be cultural appropriation.
