“Did you hear what Trump said about keeping Muslims out of America?” I asked my son the other morning before school. He was looking at the L.A. Times Sports section while I made breakfast. It was the week after the mass murder in San Bernardino, and we hadn’t talked about it. Maybe because I’d been too anxious about all of it, or too busy with getting life taken care of — kids to school, work done, make dinner, repeat.

“Well, they do sort of want to kill us,” he answered softly. His face said, “isn’t that a reasonable move?”

My stomach dropped as I questioned my bona fides as a parent: Had I allowed my child to become a xenophobe? Where had I failed?

Actually, I understand how a young teenager could feel this way. If you read headlines that “Islamic terrorists” are killing people around the world and down the freeway, it is not irrational to agree with the simplistic sentiment “we should stop letting them in until we get to the bottom of this.”

Folks are scared. So the plain notion — keep ’em out, lock the doors — makes sense, unless you read beyond headlines. Unless you are aware of history. Unless you remember America turning away Jewish refugees, and interning Japanese Americans. Unless you know context. And as his mother, that’s where I come in.

I confess, we haven’t talked much about terrorism. His world view is based on many things, but he doesn’t know what I believe, and he needs to know. He may not know that while terrorists claim to be “Islamic” they do not represent Islam. It is not top of mind that targeting any religious group – creating registries, shutting down places of worship, banning refugees – is 100% contrary to American values, and our Jewish values.

I am ashamed of my omission. I grew up in a home where we debated politics, where my parents taught us about initiatives or candidates they supported or opposed, and why. I thought I’d recreated that home just by being myself, but clearly I hadn’t. Or not enough.

How did that happen? It dawns on me that, unlike my parents, I shield my kids from many aspects of my life rather than incorporate them. Where my mom schlepped me with her to the market or dry cleaner or political rally, I go to the market — and call my Congressman — while my kids are in school. It’s easier for me. But the consequence is I am not transmitting my values. We miss opportunities to talk. And in these times, it is more important than ever to talk about what we believe, what kind of world we want to live in.

Back in the kitchen, my heart raced as I envisioned my son slipping into the darkness of Trump-ism because I hadn’t taught him better. I had one minute to set him straight before sending him off to school. I trotted out everything I could think of, not sure what might pierce his focus on the NFL match-ups for the weekend:

“Islam is not a violent religion. Most Muslims are peaceful.”

“Muslims are just like Jews and Christians. We’re cousins!”

“If a bad guy was a Jew, that wouldn’t make all Jews bad, would it?”

“Remember when we visited Manzanar, the internment camp? That’s what happens when we scapegoat an entire group of people, when we act based on fear.”

“Even Dick Cheney thinks Trump is off his rocker!”

He puts the paper away, ties his shoes, and I take a breath.

“Did you hear anything I said?”

“It’s okay, Mom. I understand.”

There is so much more to say. I want to tell him that the world is a safe place, despite the headlines, and that we do not have to live in fear, or act out of fear.

I need to work on my speech, but the conversation has started.
