This says it perfectly.

1. It ocured to me recently that Rs using that word is an insult to people with disbilities

We don't use the word retard anymore. It is offensive and mean and we just don't do it. But low class people will so I guess that is why they continue to use a version of it as an attempt at a "put down" toward liberals. Liberals would never use any version of a word like that. We just have more class.


That being said I like what he said.
