that's my beef with rachel maddow, only she does the same thing verbally. i don't mind her opinions whatsoever, but the presentation is insulting and unwatchable
done right a non-objective approach to journalism/opinion can expose "deeper" albeit arguable conclusions: i highly suggest reading The Electric Kool-Aid Acid Test by Tom Wolfe. he dispenses with objectivity at the very outset of his narrative but makes a strong case for what i can only call "honest subjectivity"
the flip side of this is Into Thin Air by Jon Krakauer, which is a gripping read but a really sorry exercise in journalism as self-flagellation
