I was addressing the whole definition, both the second and the first part. Taken together, they both largely seemed to leave racism by non-whites out of the picture. At least that was my initial perception. It’s hard to say that many non-whites have ever viewed whites as inherently inferior from the traditional biological/intellectual standpoint.

On the other hand, as I Am Jim noted, there is a widespread perception among the “woke” types that being white is a strong determining factor of moral inferiority. This gives rise to the anti-white prejudice I’ve spoken of before. Those who hold such a belief could, under M-W’s first definition, be therefore described as racist.

I agree, any change in the dictionary definition of racism should not exclusively refer to the “social justice”-based view of it. As long as they’re simply adding to the existing definition, that’s not necessarily a problem.
