I think others are confusing your "lower IQ" comment to mean "people with intellectual disabilities", which I don't think you're defending. It's obvious that "stupid" people (those seen as "normal stupid") are one of the last publicly-acceptable targets of ridicule. It's common for even the most well-mannered public personalities to speak derisively and dismissively about the stupidity of others. The most common insult toward someone you disagree with is to call them "stupid" or "an idiot". No one says "retarded" in polite company anymore, but it's essentially the same thing.

Funny that you mention it, but at one point "mentally retarded" was a gentler term for the then rather harsh clinically-used terms "idiot", "moron", and "imbecile". Now these three words are considered much less offensive than their one-time euphemism. What a world.
