Presently, I am listening to Rush justify his aforementioned mocking yesterday of an 18 year old Inuit girl's testimony on the effects of global warming on her community.

His justification amounts to this. He claims for himself the right to criticise testimony before Congress, and won't apologize for doing so.

He's correct: he has that right. And he should criticise such testimony.

Mocking a girl for crying during her testimony, however, is not the same as criticizing (or critiquing) her testimony. There is a distinction. Limbaugh should make it also.
