Stephan Stowe, 17, was charged with harassment after telling Jewish rider ‘They should have killed all of you.’ Police also wrestled a woman to the ground and arrested her after angry onlookers swarmed the station’s platform, snapping video and yelling at cops during the incident. The attempted arrest of an allegedly hate-mongering teen aboard a Brooklyn subway quickly turned into a wild showdown between cops and a roiled mob, according to sources and video obtained by the Daily News.

The melee began when suspect Stephan Stowe, 17, and a group of eight friends approached a Jewish man wearing a yarmulke aboard a Brooklyn-bound 3 train just before 3 p.m. Monday, police sources said Wednesday.

“Assalamu Alaikum,” Stowe said to the man, using a common greeting among Muslims that means, “Peace be with you,” court documents allege.

When the man ignored the greeting, Stowe allegedly became combative.

And you Yanks think Southerners are effing crazy?
