You want to know the most ridiculous aspect? Without Russians propping up their nonsense, it really is just a relative few nutjobs and liars (as in they know its bullshit, they're just doing it to stir people up to sell them other bullshit) that are pushing this garbage.
Some of these nitwits really believe that they are a majority in America, because they're having Russian bots echo shit back to them on social media, making them think they're really getting people hooked (and playing up their persecution complexes). To be fair, the Russian propaganda machine has been helping the nutjobs and shit-shovelers get their message out to the general populace, and a swath of America was uncertain enough to actually believe it for a while. There is going to be a breaking point though. Sadly its probably going to take a catastrophe (like another Oklahoma City bombing, it'll have to be big, and it can't be just guns because we know Americans aren't willing to do jack shit about that no matter how terrible it gets) for that to occur.
