Mayor of London Sadiq Khan delivered a remarkable speech at the South by Southwest, or SXSW, conference on Monday — remarkable for bad reasons, not good ones. He said that he wants social media companies to crack down on free speech.

Following his speech, Khan was interviewed by HuffPost editor Lydia Polgreen, who at one point asked how we can be “better citizens in our global democracy” (and people wonder why Trump won!), Khan offered thoughts on Trump and his war on Uber. But the most telling moment came when the mayor stated that “As a former human rights lawyer, I’m a big advocate of free speech. This isn’t about depriving people of free speech, this is about inciting hatred.”
