The fast pace of globalization with all of its benefits is also accelerating the viral spread of hatred. Where once regional enmities brewed for centuries with sporadic outbursts of warfare and imperial powers that waxed and waned, the truly global speed and scale of ideological hatred and international conflict was not possible until recently for many practical reasons.

A few weeks ago, USC Student Body President Rini Sampath posted on her Facebook page about incidents of hatred and intolerance on campus. A Saturday night after a USC football game, Sampath had been walking down USC’s Fraternity Row when a man leaned out his frat house window and hurled a racial epithet and a beverage cup at her.

You’re never too old to learn about cultural diversity. I realized this over the weekend, on the eve of Hanukkah. My mom, a fourth grade teacher, told me about an incident she’d just experienced at a local party-supply store. She was shopping for her annual Hanukkah lesson, in which she briefly teaches her students the meaning of the holiday, demonstrates how she lights our family menorah, and leads them in a spirited game of dreidel. Everyone goes home with a little bag of chocolate gelt, a dreidel and maybe a Hanukkah-themed pencil.

Much like testimony shows how regimes have constructed borders; testimony demonstrates how individuals can construct bridges to connect with people of different beliefs and identities.

What I’ve learned, looking back at my family history and while working at USC Shoah Foundation, is how to do resistance. That’s how you do resistance. You see injustice and you tirelessly fight against it.
