The weekend after surviving one of the worst school shootings in American history, a few students from Marjory Stoneman Douglas High School met up for a slumber party and vowed to change the world. The goal was sensible — real gun reform. The battle, the kids instinctively knew, would be waged on social media. The #NeverAgain movement was born: a youth-driven, politics-conquering triumph that proved beyond doubt the establishment is no match for a committed group of teens fighting the good fight. The group's cofounders won Twitter this year by hitting hypocrisy head-on. They dispatched Alex Jones conspiracy wacks with alacrity. They doled out memes, spanked down GOP naysayers, and organized millions to march for gun restrictions. Corin has been among the most effective in the group, blending an earnest call to action with a sense of humor and willingness to tussle. "If you are a student in Florida, print this tag and wear it to school. Remind the world that you are worth $1.05 to @marcorubio," she tweeted with a link to a price tag, referencing Sen. Marco Rubio's millions in NRA donations divided by the number of students in the state. No wonder Corin has tallied more than 160,000 followers in just a few short months.
