The second set of images shows another crowd, thousands of miles away from the first. This crowd is full of men and women, all ages and all races, and they’re waving American flags and rainbow-colored flags. This crowd isn’t flanked by gunmen; no one looks frightened or enraged. This crowd is laughing and embracing; a few people are weeping, their faces lit with relief and joy. Caption from the Washington Post: “Gay rights supporters celebrate outside the Supreme Court in Washington after justices ruled that same-sex couples have the right to marry, no matter where they live.”

I know which crowd I’d rather be in.

Do you want to fight the Islamic State and the forces of Islamic extremist terrorism? I’ll tell you the best way to send a message to those masked gunmen in Iraq and Syria and to everyone else who gains power by sowing violence and fear. Just keep posting that second set of images. Post them on Facebook and Twitter and Reddit and in comments all over the Internet. Send them to your friends and your family. Send them to your pen pal in France and your old roommate in Tunisia. Send them to strangers.
