Behind a barricade, a group of men wore the fringed Jewish prayer garment known as the tzitzit and held up anti-gay signs bearing the logo of a group calling itself the Jewish Political Action Committee.
“Judaism prohibits homosexuality,” one sign read.
But the men were not Jewish. They were Mexican laborers, protesting because they were paid to protest, said one of the men, who would not give his name.
Heshie Freed, a member of the political action committee, an Orthodox Jewish group based in Brooklyn, said that the men were supplementary troops, filling in for the Jewish students who would normally be called upon to demonstrate.
“The rabbis said that the yeshiva boys shouldn’t come out for this because of what they would see at the parade,” Mr. Freed said.
