Ms. Peterson, who was born in West Berlin in 1946 and became an American citizen in 1982, said she took offense to the comparison of Mr. Trump to Hitler.

“They said Trump is a second Hitler,” Ms. Peterson said. “I said do you know what that sign stands for? Do you know who Hitler really was?”

“I make the point that they are demonstrating something they had no knowledge about,” she said. “If you want to do it right, you do it right. You don’t know what you are doing.”

That is when she made the Nazi salute — a gesture that is banned in Germany — as a form of counterprotest. But that is all it was, she said.

“Absolutely I’m not a Nazi, no,” she said. “I’m not one of those.”

Sounds like a reasonable response to the situation.
