One student was teased about being a “brown, bald lesbian.” Another was the target of conspiracy theorists who claimed he was really an actor. When a group of teens posed for a photo, they were accused of lapping up attention from the news cameras and “partying like rock stars.”

Just days after watching their classmates die, survivors of the Florida school shooting came under a different kind of assault, this time from online trolls who threatened the students as they seek tighter gun laws.

In the face of such attacks, the students have been undeterred, confronting the trolls head-on in television interviews and on social media.

“They see us as a threat. And honestly, that’s kind of entertaining to me. And I love it because it means what we are doing is working. We are changing the world,” student David Hogg told MSNBC on Wednesday at a rally outside the Florida Capitol.
