It seems to me, that, even accepting Russian interference, to say that the interference was strong enough for explaining the results, instead of other factors, is just ridiculous, and the burden of proof should be in the proponents of that theory. It seems to me, that people all around 'the West' is angry because 'the establishment' have failed then. Instead of changing their ways 'the establishment' have decided to find a scapegoat and, in fact, blame the system. When democracy don't give the results we want, we are not so democrat anymore. The result of this discourse, the subtext, is: "see what they voted? how they dared to vote outside the program? you can't trust voters anymore". That sounds like a very dangerous message to me. By the way, as a non American, I think that the irony of USA complaining about interference on internal electoral processes is really high.
