That more democracy is more attackable is not a coherent position. More democracy means more people power. But people being powerless to resist misinformation campaigns means that they do not have power. Which means that it is not really democracy. This is the same as saying that democracy is being undermined by wealth inequality. If money can buy political power and money is unevenly distributed then it’s not a democracy.

If one was actually interested in actual democracy one would fix that misinformation asymmetry.
