Contentious or provocative viewpoints are shared every second of the day online. That’s not to say, however, that an opinion is less valid simply because it’s initially unpopular: just think about Galileo or Emmeline Pankhurst.

Our #WakeUpWednesday guide explores the crucial differences between free speech and hate speech.
