Dude, you need to take a pause and read up on this. It’s your civic duty to be informed and you are so very wrong about everything here.

Inciting violence is very different from defamation/libel.

No, lawmakers making false statements is not defamatory nor libelous. In fact, they have complete immunity while on the debate floor.

And defamation/libel have to be knowable false statements of fact which created demonstrable damage. Opinions can’t be defamatory. True statements can’t be defamatory. When Trump’s Chief of Staff, General Kelly, calls Trump a fascist and lists the definition of fascism and saying that he meets each one, that’s neither false nor inciting violence.

Maybe check your priors to see if you are more mad because people aren’t being prosecuted, or because what they are saying has truth to it.
