No social media platform gets more hate than Twitter, which has become fertile ground for trolls, white supremacists, and just plain assholes — especially in the age of Trump. But not everyone is using 140 characters (or less) to bully, harass, and hate. Some people still see it as a tool that can be used to connect and galvanize.

Nowhere is that more apparent than on Black Twitter, the viral community of African-American Twitter users who’ve turned their non-stop tweeting into a political act, spawning influential protest movements like #Blacklivesmatter and #Oscarssowhite along the way.

But don’t take our word for it. On Monday The Daily Show’s Roy Wood Jr. explained this cultural phenomenon way better than we ever could, and he did it in a barbershop, to boot. Joined by Black Twitter gurus Elon James White and Jamilah Lemieux, Wood Jr. likened it to Harlem: “Black folks made it cool, and now white people are trying to move in.” Lemieux says that Twitter is the “first thing that black people have effectively appropriated and made our own” and that “they should just give us Twitter.”
