This all started with Facebook. Those "opinions" are partly manufactured in russia and for russian money amplified through US owned social networks. Any "opinion" that sows discord in the West is used. Content is pretty much irrelevant. The outcome is what matters. Divisions, reduction of trust in institutions and leadership. It works because there are people in the west who opportunistically politically capture audiences created by this discord. And they do it, by repeating same "opinions", often even for free.
