Russia didn't fuel Brexit. There's a long history of skepticism towards the EU in Britain. The idea that Russia could move the needle on British public sentiment towards Europe to any measurable degree is crazy.
We need less panic about what terrible political opinions people might voice and more trust in freedom of speech.
And there's no evidence that Russia tipped Britain over that edge.
Britain's relation to the continent is something that people in Britain have a long history of having strong opinions about. It's utterly implausible that Russia could effect a 1% shift in public opinion on such a vital subject.
There was an intense, years-long debate inside Britain about EU membership. Trying to blame Russia for that is just ridiculous. It's a demonization tactic used by people who are upset about their countrymen's opinions.
