Calling someone or something "racist" should be done carefully.
Not anymore. It is now a simple (and often effective) way to try to silence others, or to shut down policy that is against one's own ideology.
For example the voting law that went into effect in Georgia. Didn't favor the left, so as expected they immediately called it racism, just like they do with everything else. That is the new move.
Being called a racist carried some weight, but it's getting to the point where it will be meaningless. It will get much worse before it gets any better.
