My first point was that liberals, particularly colleges, often define racism in such a way that only whites can be guilty of it, at least in America. That’s a quote from a mandatory indoctrination session from the U of Delaware. And it’s by no means the only example.
This definition is based on the notion that racism is an expression of power. Since only whites have power in America, only they can be racist. This notion looks a little silly, to be sure, at a time when our President is black.
My second point was that the primary dictionary definition is one of a belief in superiority, so you can hate and kill another race all you want without being racist, as long as you don’t believe them to be inferior.
For instance, some (not all) Nazis recognized the great intellectual accomplishments of the “Jewish race.” They didn’t believe Jews to be intellectually inferior, they just believed they needed to be destroyed because they were a threat to the “German race.” By the primary dictionary definition, therefore, they weren’t racist.
Now it should be fairly obvious I believe both these arguments to be nonsense on stilts. They are merely examples of how, if you allow someone else to control the defining of words, they can be used to damn you while excusing everyone else.
