You are entitled to your own opinion, and you are entitled to make up your mind based on whatever you think is interesting and significant.If you find out that someone is a liar, you don't listen to him but unless libel or slander is involved you usually can't sue him. That is, the government will not punish someone just because you do not consider him a reliable source. If you decide that you don't agree with my perspective you can't get the government to punish me because of it.
Ultimately there is no downside to lying to you other than your own decision to ignore the liar. It's up to you to read between the lines and decide who is reliable as a source on what topic(s). This is the perspective which accords you the reader maximum respect. The opposite perspective tells you, "Don't worry your silly little head about things, sonny - I'm here to tell you the truth so you won't strain your synapses thinking for yourself."
The frankly opinionated columnist writes up to a critical audience and expects reasonable people to differ; the leftist writes down to an audience of presumptive sheeple who have to be led by their betters. The journalist fits the latter category, and styles the former to be "not a journalist, not objective" when the frankly opinionated columnist is typically far more reliable than the "objective" journalist usually is. The "objective journalist" occasionally will misstate or lie, but more often will tell half the truth and cause you to jump to the wrong conclusion. You will be more likely to look for that - and know where to expect to see it - in the frankly opinionated columnist's work. And for that reason the latter is more on his mettle to guard his reputation with you.
Lemme phrase it another way... Unless I know someone to be a habitual/chronic liar, I'll generally accept what they say as true. UNLESS it involves matters that could have an effect on me, others, or even society; and more importantly, do I care. If I care, it becomes a matter that requires investigation. Here's the kicker; too many people don't care. The useful idiots on the left don't know, and furthermore, don't want to know. Most conservatives, if they think about it at all, discount it and move on, rarely sharing their misgivings about the faux press.
Gotta run.
