It is still a fallacy though.
Let me help you understand how to stop fallacies:
X must equal Y because Variable M that does not require under all circumstances that X must equal Y given the presence of Variable M.
So for example, does news corp or the wallstreet journal ALWAYS lie? Obviously not.
What is more, MUST they lie? For example, if we had a computer program that reported on a binary value and it always gave the opposite value to whatever it read. Then you could conclude that variable X was the opposite of whatever that program said. Neither newscorp nor the Wallstreet journal are reliability reporting the opposite of anything.
Therefore it is logically fallacious to say that something they said is a lie because they said it.
See?
Fallacies are about LOGIC. Not you fucking politics.
You can't say anything is automatically bullshit no matter who says it because no one is reliably wrong 100 percent of the time.
You can of course take what they say with a grain of salt. You can choose to ignore them. You can hold any sort of opinion you want.
You cannot say that everything they say is wrong or that any given thing is wrong simply because they said it.
You have to actually wade into the issue and form a discrete opinion of it.
If you can't be bothered to do that, then your opinion is based entirely on your own bias and the value of your opinion is based on the value of your bias. Which in this place is literally nothing.
