"It’s nearly impossible to change the country. The only way that that could possibly happen is if that’s a mass movement. If my mom can’t come, we’re not going to change the country. That’s the bottom line. We could spend days debating what ‘violence’ means, but when we boil it down, when someone smashes a window that means no one’s mom is coming, and we need the moms to come."
