Can you please provide data that supports this statement?
>Untrue facts about guns for example are never pointed out.
Using absolutes such as "never" in a statement like that can often be a bit of a stretch. Like my last question, do you have proof that Facebook has never fact-checked a single gun video?
What kind of data do you believe would be necessary for a negative claim like this?
Do I have proof there is no teapot between the Earth and the moon? No. Do you believe this means you can dismiss my claim that there isn't a teapot floating between the Earth and the moon?
It's literally as simple as a total count of left-leaning and right-leaning posts/videos/photos that have been fact-checked.
You'd have to also determine the respective frequencies of left-leaning and right-leaning posts/videos/photos containing falsehoods for those numbers to be useful.
I am correct, because you cannot find a single video on Facebook which posits the existence of said molemen. Therefore, Facebook is censoring those videos.
In more detail, “liberal” in US politics has a lot of conflicting uses and is almost a useless term. The US Democratic Party is dominated (though somewhat less so today than a few years ago) by a neoliberal, centrist (arguably center-right) pro-capitalist faction, which tends to also be where the most consistent support for gun control in the Democratic Party, or mainstream US politics more generally, is.
It’s next biggest faction (the closest mainstream US politics has to a “left”) is a center-left social democratic faction (some of which self-identifies as democratic socialist); this faction has a mix of people who are less supportive of gun control than than the neoliberal faction of the party, and those that favor more extreme gun control, and everywhere in between.
The actual American left, which is largely outside of the major parties, is also quite mixed on gun control.
