Remember Frank Muir's description of Joan Bakewell as "the thinking man's crumpet"? That sort of language would not be acceptable in polite circles today, but it was meant as a compliment, and I'm sure Ms. Bakewell didn't object too strongly at the time. Autres temps, autres moeurs, as they say.
So how would I describe Ms. Abby Martin? Her "Breaking the Set" is a regular feature on "Russia Today". She doesn't pull her punches. I'll just call her the angry leftie's commentator of choice.
