I think it is a bit more insidious than that. For all of the railing that Americans do against the government, they still believe that it can protect them. Without the government they wouldn't have the military which keeps American interests safe. Extrapolate that feeling of government providing some measure of safety, and you have a problem where I think many believe that if Russia really was interfering with Facebook, Twitter, et. al., then the government would come out and do something about it.
Right now, I believe proclamations about interference affect every American in roughly the same way. "Oh those bad Russians. It's a shame they are duping those other idiots on these platforms, but not me, I and my social media friends are too smart to fall for that."
Much of it stems from
humans inherent nature to be terrible at evaluating risk. What isn't covered by our poor risk estimation, is then impacted by our
inherent nature to overestimate our own capability. Social media seems almost like the perfect melding of marketing, psychology, sociology, and evil designed to take advantage of everything we've learned about human nature over the past 100 years and weaponize it into creating the perfect system to foster tribalism.
