CNN promotes BLM/Antifa (the rioters, not just the peaceful protesters). Both groups say on their website that they are Marxist organisations and want to destroy capitalism and the Nuclear family. CNN supporting such a goal is inherently far left.

I don't know if they do this for ideological reasons, or if the outrage machine makes them a lot of money. My guess would be the latter.

Antifa isn't a centralised group, let alone do they have a website that speaks on their behalf.

CNN sympathizes with their cause not their organizations.

I do too, but CNN are clearly turning a blind eye to the organisations behind the cause. I will actually ascribe this to most major networks, not just CNN.
