I agree no pandering and was not suggesting that. Agree also with contempt. Thus using their venues of record is not the avenue in either case.
I would counter that by pointing out that a) these are venues that the public is familiar with and already accepting to views coming from these venues and b) by using 'alternative' venues it is very easy for the left to mount a "vocal shunning" movement to label these as 'wrong' 'right-wing' and 'not-cool.'
These reasons support the use of familiar and long-standing media venues.
