Froma is probably the dumbist of the dumb. Meaning she can’t even get a gig on MSNBC
I take your point, but if you're going to be throwing around insults about the intelligence of other people, I suggest you check your spelling before hitting the "post" button.
That is, unless you meant to suggest that Froma is a follower of the philosophy of Dumbism, in which case carry on. Although do watch your capitalization.
