The interference really was only the leaked Clinton emails, the facebook propaganda is just typical propaganda nobody really pays attention to unless it's to confirm their own bias, nobody anywhere changes their political opinion because of something they read on facebook. I doubt Russians had any real influence, the question is those leaked emails, which everybody wants to know the provenance. Personally I think it was just some DNC pro-Bernie activist staffer, who burned from the primary shenanigans decided to leak to Assange and not Russians, (because we all know those radical DNC tech staffers are bernie bros (now Yang shills) from SV) despite the nonsense indicators of compromise that the FBI never saw but was only provided by the DNC themselves. Even if you believe that was a major influencer I don't think so, as a neutral foreign observer of US politics I saw a wild card that the Americans were ready to put into office to 'disrupt' as a protest vote because if anybody remembers, they were only given two choices before the disruptor, Clinton 2.0 or Bush 3.0. They responded accordingly by pushing the maniac into power just to implode the system from what my foreign analysis indicates.

I think the most dangerous propaganda are the news propagandists from MSNBC and other networks who pretend to be from your specific subculture/groups, and then feed you lies and propaganda. That to me is the most dangerous, the Russian bots? nope everybody sees through cruise control shilling but when it's somebody from their own group in a news org and they're spouting lies it's a lot more difficult. I'm old so back in the 1990s news propaganda was just absolutely blatant, any kid could tell Norman General Swartzkopf(spelling) was making up bs about 'precision bombs' we all knew they were just landing wherever and blowing up Mother Theresa's Iraq orphanage by accident, but now it's different. The news corps discovered they need to recruit people from specific identities and use them as a weapon to feed lies to their subculture.
