TROUBLING TIMES: “It’s sad; it’s depressing,” said Imam Yama Niazi of the travel ban and its marginalizing effects on Muslims. But he’s trying to keep his sermons positive and his followers hopeful. “We’re American, we’re patriotic, we’re here, and there’s nothing you need to fear,” he said. Niazi and other S.B. religious leaders have planned a peace walk on 2/4 from 2-4 p.m. starting at the De La Guerra Plaza.
