How do you distinguish between opinion and propaganda? Its entirely credible that Pepe Escobar sincerely believes the positions he holds.

Oh, so if he sincerely believes in genocide, it’s fine.

Should the corpus of every news source that includes opinion pieces that serve the interests of a war criminal state be banned?

If they continuously make naked apologia for that war criminal state’s war crimes, especially ongoing ones, and parrot the propaganda points pushed by that state which clearly and directly contradict reality, yes, absolutely.
