Tell me then...how is mocking someone for failing a "simple" yet scientific test considered offensive, but tossing out a "tard" for an equally scientific condition NOT considered offensive? You guys don't post "mentally retarded liberals"...you post "libtard". Is "tard" not offensive? Even when directed at someone who has a loved one that was given that "scientific label" back in the day? The use of "tard" is just as offensive as comments about Alzheimers, but I'll bet it never crossed your mind. Heck....you might even have thought it's funny. Let's say that those stupid, overly sensitive liberals didn't prefer the more "politically correct" term of developmentally challenged, and instead, mental retardation was the term of choice today. Is 'tard' still okay?
