Opening Eyes

Note: I am not, in any way, intending the following to be offensive. I am simply trying to make a point and help open some eyes in the process.

If you were discussing negotiations about purchasing a car with a friend, would you use the phrase, "Jew them down."

If you have children, will you teach them these words to this nursery rhyme? Eeeny, meeny, miny, mo, catch a nigger by the toe."

Then why is the phrase, "That's retarded." okay?

Please realize I'm not an advocate of always being politically correct. However, I do think it is important to think before we speak.
