As an American, I would characterize FOX as having a "wink and a nudge" relationship with the extremists, including neo-nazi groups and white supremacists. They don't overtly support those groups, but are sometimes apologists to their cause. These groups are a loyal part of their audience base. You gotta' feed your base.
In relation to Ukraine, FOX editorial talking heads were on Putin's side, especially Tucker Carlson, until the invasion. Now they are backpedaling, and have taken the position that the invasion is a bad thing, and is the fault of Joe Biden's weakness, and that Putin wouldn't DARE invade Ukraine if Trump were still President.
MSNBC is the opposite, but not as good at it as FOX is. FOX has propaganda down to an art form. MSNBC is kind of a liberal FOX wannabe.
