Here's my theory on that mentality, many of the people who have the viewpoint of 'Russia bad' are baby boomers who lived through the cold war and Clinton was one of them. If you read through her emails and you check out what an actual general was saying about establishing a no fly zone in Syria and how that would cause a war with Russia if they had to shoot them down you will suddenly understand why they say the things they do and why they blame Russia for literally anything.
Clinton was the pro-war candidate, not Trump.
