Fourteen members of the family were on weeklong reunion in South Padre Island when the man, who was identified in a police report obtained by BuzzFeed News as Alexander Downing, of Waterford, Connecticut, approached them.

"You're a fucking Muslim, motherfucker," the man says at one point in front of the family, which included children playing on the beach, just feet away. "You will never ever, ever, stop me, my Christianity," the man says, "from rising above your Sharia law. Your Sharia law don't mean shit to me."

Sharia — a religious code of conduct, no different than those contained in other Abrahamic religions — has often been used as a fear-inducing term associated with anti-Western beliefs in recent years.

The incident, which was captured on video by Noria Alward, 19, and posted on YouTube, shows Downing, intoxicated, approaching the family in an aggressive manner — repeatedly shouting obscenities and veiled threats while pointing his finger in their faces.
