When people say MSNBC is on the left and Fox News is on the right, they are misunderstanding what Fox News is. Fox News isn’t an honest conservative news network, it acts as the propaganda arm of the Republican Party. Its creator cynically created Fox News to spread bullshit in favor of his ideology.
MSNBC had a liberal bent, but its hosts don’t go help a current or running president campaign. Each host has his own thing, but there isn’t an overarching propaganda goal to the organization.
Fox News may be unique in the Western World when it comes to a supposed news network designed as a partisan and ideological propaganda arm.
