It's sort of like saying fake news. It's easier than changing your position when confronted with inconvenient facts.

rocks are hard, water's wet... no one denies those facts.

But if someone suggests that Seth Rich shot himself twice in the back of his head..... and Snopes calls it false, does that make Snopes left or right leaning?

How is that quest for "value free facts" going for you?

I think the real point of snopes is that it includes a lot of the information you may want to consider when exploring the truth of something. Is it okay to disagree with Snopes? Sure, but you should indicate what facts it isn't taking into account or which inaccuracies are included in its write up. This lets you have a more substantive discussion than just believing the original claim or just dismissing Snopes as fake news.
