I've been doing this. Liberals do not know how to respond when you throw these terms right back at them.
Ya. It is kind of fun to see the reaction on their faces. I kind of nullifies the word “racist.”
I point out to them that by claiming racism, they can’t see people with color blind eyes. All they see are “black people” or those evil “white people” and not individuals and good people. That makes them racists.
