I'm not a fan of Sacha Baron Cohen, don't find his humor funny most of the time. But on the issue of free speech, freedom vs. hate speech and lies, I totally agree with him. He gave the keynote speech at the Anti-Defamation League's summit. The Washington Post has a shortened version, but it's behind a paywall.
I agree that Facebook, Twitter, and other social media sites should better monitor hate speech and remove the lies that Trump and others post on these media. He's right that we're losing our respect for facts and truth.
