We should look at ourselves instead of Trump
This is an undeniably difficult problem, but I think the real issue is deeper than Trump, it is about educating and empowering voters. Trump is a symptom of a cultural and educational challenge.
Attacking Trump publicly will only force him to double down on his lies, radicalizing his rhetoric and pulling his constituents ideologically behind him. Attacking Trump supporters only entrenches them in defensive resistance. No one likes to be told that they are stupid.
The real solution is to educate people gently and nonthreateningly to listen to real information and fact check. To build opinions on their own via multiple disparate sources.
Politicians have always had to lie. It’s part of the game. Fact checkers rate Obama’s truthful statement percentage during the course of his campaign at 75%. Trumps rating is around 30%.
Unless we can educate citizens and empower citizens, we will always be lied to, by one source or another.
