Maeen Ali remembers the worry he felt when he first spotted the “Punish a Muslim Day” screed online.
The letter, mailed last spring throughout England, encouraged violence that ranged from pulling off a woman’s head scarf to bombing mosques. Each attack, the letter instructed, would be rewarded with points. The hate campaign prompted thepolice in New York and other big cities to expand patrolsaround mosques and Islamic centers on the specified day.
Mr. Ali, who lives in Downtown Brooklyn,said he was consumed by thoughts of his four children’s safety.
“That just boiled inside of me,” said Mr. Ali, 38, who moved to the United States from Yemen in 1990. “That’s when I said to myself that it was really important to come out and protect Muslims in the community.”
