Wow. You're actually equating 'comedy' with horrible people threatening to rape and kill elected officials? 

Being critical of our leaders and public figures, left and right, is called 'Freedom of Speech'. Threatening to harm them, or a group of people, is called 'Hate speech'.

John Oliver comedy bits doesn't lead to massacres at a mosque in Quebec City. Fear-mongering by Le Pen, Trump et al demonstrably does.
