That's a tricky question. I want to draw a distinction between the cut and thrust of domestic political actors who talk to their constituents and foreign disinformation. The appropriate response to those things, I think, is understandably different.
I agree with the general premise of what you're saying, which is that in an ideal state, our democracy is based on evidence and facts, and voters are informed correctly. What is true and what is false in a domestic debate context is subjective, of course.
