I mean, if your argument is that we have uninformed people in America, I certainly won't disagree.
That's different from the argument that "Americans don't understand civics because they watch movies instead of reading history books" which is frankly absurd and offensive.
I'm not convinced that the number of civically-uninformed people is particularly higher in America when compared to elsewhere in the world. If you have data to that effect, please share it.
For all intents and purposes the election is done. The votes have been cast and with most of them counted, Biden has won by a wide enough margin that sporadic concerns about voter fraud is not going to change it.
Americans who are pushing back against Trump's reticence to concede are not doing so not because they believe that TV decides who is elected, but because it's a bald-faced attempt at a coup. Trump has every right to challenge the results in court, but if there was actual evidence of widespread election irregularities, it would have been presented by now.
