Fox News is, and has forever been a propaganda outlet, for conservative/reactionary news spin, practicing political/journalistic malpractice on its viewers. And, it is thoroughly intentional.
MSNBC, on the other hand, is not doing its job from your point of view. Which is not an unusual opinion and one I generally share. But, these arguments/critique are not the same thing, at all. Omission is not the same as comission in business, or life. A reputable business selling mattresses doesn’t instruct its representatives to trash the product it’s pushing. It merely requires they sell the upside and not lie in doing so.
" Caveat emptor " does not allow false representation, by law. And, there are many laws and remedies, to prove that. What Fox did with this photo is " ipso facto " a blatantly false representation.
Your false equivalency is the same as what Fox News does regularly. Their motivations are pretty obvious. Unfortunately, yours are too.
