Ignoring Bob Costas, and those like him, is the civil rights equivilant of ignoring al qaeda in the 90s.
Imagine a political cartoon in the Sunday paper.
In the distance, the Twin Towers stand, one labeled "Heller", the other "McDonald". In the foreground, a jumbo-jet, headed for the Towers, labeled "Bob Costas".
Doesn't have to be him, could be any of an untold number who think like him. He just has a MUCH larger voice than most.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
-Jim Eliott, paraphrasing Philip Henry.
