This issue has been discussed.

One might (still) not like the tenor of the way Olbermann says or does anything - that is a subjective matter, a taste. Dad said that there is no accounting for taste. Still, the objection denies the objective and the empirical.

It’s one thing to say that you don’t like Olbermann, but if you can’t tell (or worse, lack the character to admit that you know) who is lying and who is not, that can’t be helped…a shame none the less. The difference is those who conflate Olbermann’s style with Olbermann’s content give comfort to those who willfully spread dumbth, polluting our national discourse.
