Getting upset about the definition of words when they don't fit your privileged view of the world is a common tactic of those in places of privilege when equality seems to attack their base of privilege.

You don't understand racism at all. That's not even the dictionary definition of it. Any of the dictionary definitions of it.

Racism is believing that one race is superior and basing the oppression of other races upon that belief.

Thus, the oppressed cannot be racist. They can be intolerant or bigoted or any of many other things; but they cannot be racist because they are not coming from a position of privilege to even be able to oppress.
