I didn't mention Facebook, but since you did, it is a cesspool of BS conspiracy theories too. It may or may not have leaned more liberal from the management at one time, but certainly does not now. We do know that Russian and other trolls have been posting there almost constantly for many years.
Anyone who gets their "news" from X, Facebook, Truth Social is a grossly uninformed person. Fox and Newsmax are admitted liars regarding the 2020 election and Trump. MSNBC, CNN are very biased in the other direction.
I use AP News as a primary and a few others that are pretty non denominational / objective sources. If more people did this, we would have a much more informed population and a much less angry population.
