"I know there have been some encouraging signs. I think people have come a long way even since I started cartooning-I mean, gay marriage wasn't legal when I started. I think our collective vocabulary for social justice issues has improved over time. So on a cultural level, we've made some progress. That keeps me going. I've had people tell me that I've radicalized their teenage daughters. But a lot of what I'm doing shouldn't even be considered radical."
