We know this doesn't work, and it's insane Americans still pretend it does. Goebbels himself said it while they were abusing the Weimar German freedoms and protections of democracy to take power with violence. They were very happy to use the tools of democracy to destroy it. We owe it to our societies and democracy not to let this kind of speech in particular to prosper.

And for a more recent example, you have a presidential couple that (among a million other things) lied publicly, and admitted to it. And they're now in power because their hatred-filled lies were not checked. And the country is sliding fast towards fascism, ignoring courts to concentration camps with no records to suing media to bully them into favourable reporting to pick any other example you want. Guess the country!
