I remember protesting the Afghanistan war in 2001 when the war was incredibly popular... with the Democrats. With the right wing, it was a fucking Jihad.
Everyone, including Democratic party members called the people against the war fifth columnists.
It doesn't matter how many words you write, calling people with positions you don't agree with traitors on a foreign payroll is the most boringly unimaginative way to describe people you don't like to those you think you do.
You know why right wingers support Trump?
- they're financially hurting and don't understand economics
- things changed socially too fast for them and they're scared.
- they're hurting, and do understand economics and are happy to burn if it also burns those they blame for their current status.
- they're assholes.
- etc...
There may be fifth columnists, but it would be somewhere less then a thousand people, but honestly I think that number is closer to zero. Why buy the cow when the milk is free.
Meanwhile, the feckless DNC doesn't have to fire it's consultants, or purge the slotkins in their corner, because people are blaming Russia for American actions.
It makes listening to your enemy impossible, too. Why bother trying to win them over, or figure out what drives them so you can stop it, they're just literal traitors.
I downvoted your post because, as with all accusations of fifth columnists, it is more a post of your failure of imagination and othering Americans with political views you don't like.
The othering isn't wrong, innately, but if your answer to the question 'why are Americans becoming Nazis?' is Russia, then you'll never be able to fix the real reasons and stop the flow of fucking Nazis.
EDIT: none of the reasons above are good. But if you don't know what they are, you can't do anything about them.
This is like Germany trying to blame some other country for the Nazi Party.
