I agree with some of your points- and the effects of Russian meddling can not be quantified. But let's be real - this is the first case I can think of where online trolls got masses of people to attend rallies that were created out of thin air.
If you remember... maybe a month ago a researcher testified before congress (he has some high faulting association with some prestigious sounding group... never mind it was just him and some tech who ran his site). He testified -and Ted Cruz among others waxed poetic... about how google's search results changed the vote of millions of voters...
Kinda blows the mind that republicans can believe that banal search results swung an election...yet a coordinated campaign from the Russians... and others, had zero effect...
