not only does it not sound like TinFoil, you must understand the larger forces at work here. Here's an example. Just a few years ago if you were to have publicly espoused a theory here or elsewhere that the Russians had teams of people it was paying to sit in front of a computer, to sow vitriol into American online discussion forums, social media, etc. at large, and therefore indirectly influence our election process, and mess with our freedom, they'd have called you a paranoid nut. Yet here we are today, and many want to bury the story of Russian meddling. The danger is that the effects of this psychological warfare are very real. It serves to move our national conversation and dialogue into negative and divisive territory.
Divide and Conquer (from
Latin dīvide et imperā) is as old as perhaps 300BC. The danger of communism and it's influence is still a very real threat today. It's machinations are having a corroding effect on our society at large here in the US. Russia would love nothing more than to divide us into different races and then have us constantly at odds with each other. A divided US is a weaker US. This is a campaign of a war that is being waged on timelines of decades and century's.
So to answer your question, not only is your theory not tinfoil, it's part and parcel of the slow "boiling frog". If those forces that want to disarm the US are allowed to win and we give up our freedom, there's no place to run to, no place to hide. Although I do not believe there's some nefarious conspiracy that would effectuate your theory in the next 50 years, in the long run, anything is possible.
