The reason I made the remark you quoted was to counter the claim that anyone who says LSM ipso-facto believes Fox News is fair and balanced. This is simply wrong. A person could encounter the term any number of places on the internet, and if they object to the ways the news media behaves, whether it be inaccurate reporting or politically biased reporting, they might become inclined to adopt and use the term.
When it comes to political beliefs, people come up with terms intended to belittle people and things on the other side that they don’t like. Repugs, Tea-baggers (yes, I know they started it themselves, doesn’t matter) wing-nuts, etc., get thrown around like rice at wedding by people on the left. Both sides do it and they always have.
Where people go off the rails is in making the value judgement that anyone who uses a certain word is automatically displaying their ignorance and not worthy of being taken seriously. There are stupid, ignorant people who never use the word and intelligent, knowledgeable people who do, and vice versa.
What’s really ignorant is to take the position that use of a certain word renders a person’s opinions invalid. I’ve heard the same claim made on this board in regard to ‘social justice warrior’, a perfectly cromulent and descriptive term, especially when you consider the vigor with which many on the PC side of politics attack and berate anyone who dares evince a belief or behavior they deem improper.
The reason terms like LSM and social justice warrior are claimed to render the person using them as not worthy of consideration is obvious - it’s an attempt to shut down use of terms that are offensive and insulting to elements of one’s own politics. It really has nothing to do with how smart or well informed the user is, nor is it a reliable indicator of their beliefs regarding Fox News or any other specific issue.
I would add that oftentimes perfectly cromulent words and terms are used in inaccurate and inflammatory ways (usually by the left it seems) to denigrate, belittle or flat out lie about something or someone they disagree with politically. I cite the term ‘war on women’ used to describe someone who thinks women should pay for their own birth control as an example.
Another is misogynist. Just a few minutes ago I was reading an article on an interview with Donald Trump where he called Democratic National Committee chairwoman Debbie Wasserman Schultz ‘crazy’ and ‘highly neurotic’, (Cite) and seeing as how to those on the left any insult to a woman anywhere translates to an insult against all women everywhere, the DNC responded by claiming Trump is a misogynist and typical of the GOP’s efforts to ‘get between women and their doctor’, 'opposing equal pay for equal work (really? When the hell did that ever happen? I’ve never heard any conservative object to equal pay for equal work), and using language offensive to women.
So here we have an entire paragraphical litany of Democratic talking points and alleged Republican sexism based on nothing but a couple of insulting comments aimed at one woman and one woman only (and not entirely untrue, as anyone who’s ever seen her in any sort of extended interview can attest). I’ll believe someone who uses the terms ‘LSM’ or ‘social justice warrior’ long before I’ll believe someone who uses such laughably untrue broad brush assertions against their opponents.
YMMV.
