It’s possible to believe that the 2016 result as legitimate, and that Russian Psyops influenced the result. After all it’s incumbent on the electorate to infirm themselves and employ critical thinking in the information they consume, but at the end of the day it’s their choice. That doesn’t mean Russian Psyops is ok, it doesn’t mean CIA Psyops is ok (while noting that you didn’t actually say that they are).

As an external observer (Brit) I deplore both those who try to malign the legitimacy of the 2016 result, and the 2020 result. Even so, I hold a special contempt in my heart for those Americans trying to excuse, justify or even in some cases explicitly encourage foreign covert influence on US elections and obstruct efforts to counteract it. Those people are not even borderline traitors and enemies of democracy, they’re all the way over the line. All IMHO, and it’s not my country.
