I can't help but wonder though.
If it's now considered a slur, is it reasonable to presume that someday the mentally challenged will someday refer to each other much in the same way that homosexuals and various ethnic groups took power over their slurs? Will there be short-bus kids calling each other 'tard as a linguistic show of solidarity? Will there be throngs at rallies with posters which exclaim "We won't be departed/We're here and retarded!"?
