Lunatic Punches Woman in The Face on NYC Subway.

This video was uploaded to social media showing an unhinged man punching a female subway rider in the face in NYC.

The man was said to be angry when he boarded the subway car, telling everyone to move their kids out of his way while pushing people around.

The woman with purple hair just calmly told the man to 'chill' at which point he sucker punches her in the jaw with a closed fist.

The man then goes on a racist rant about being black, seemingly referring to punching the woman for speaking out while being white.

The woman's boyfriend was standing beside her but seemed shell-shocked over the incident.
