I was taking pictures of my daughters. A stranger thought I was exploiting them.

I walked outside to where he was standing and calmly said: “Excuse me, sir, but you just embarrassed me in front of my children and strangers. And what you said was racist.”

The man didn’t seem at all fazed. He replied: “I work for the Department of Homeland Security. And let me give you some advice: You were standing there taking photos of them hugging for 15 minutes.”

I see. So we didn’t fit the mold of what he considered a typical American family, and he thought my picture-taking was excessive, possibly depraved. How long should family snapshots take? He thought he was qualified to judge. I told him I was a professional photographer and take lots of photos.

“My wife’s a photographer,” he said. “I understand.”

“Then you should have known better,” I replied.
