This Week in Hate highlights hate crimes and harassment around the country since the election of President Trump.

For many Americans of South Asian descent, the shooting in Olathe, Kan., last month of two immigrants from India was part of a disturbing pattern. Even as South Asian American communities grow around the country, their members are increasingly victims of harassment and violence. Often, they are perceived, correctly or not, to be Muslim.

Harmann Singh, a Harvard Law School student who was born and raised in Buffalo, N.Y., was talking on his cell phone to his mother in a Cambridge, Mass., store when a man swore at him and called him a Muslim. Mr. Singh tried to walk away, but the man followed him around the store, demanding to know what country he was from.

Though Mr. Singh is Sikh, not Muslim, he saw the incident as an opportunity to take a stand against Islamophobia. “It’s really important that we all come together,” he said, to “fight against injustice against anyone and not just our own communities.”
