The creep who went on an anti-gay tirade and slashed a man in a Greenwich Village McDonald’s turned himself in yesterday, authorities said.

Keith Patron, 44, walked into the 42nd precinct stationhouse in The Bronx and confessed to the attack at 8:15 p.m., police said.

Patron had apparently changed his tune by the time he was arraigned at Manhattan Criminal Court early Wednesday morning, pleading, “I’m not a hater,” to the crowd. Patron wept openly as his court-appointed attorney tried to argue for a lower bail; he was ordered held in lieu of $50,000.

The 350-pound perp yelled “F—ing faggots!” and then slashed a 22-year-old man with a razor blade last Wednesday at 7 p.m., police sources said.

Patron was allegedly enraged when the victim’s transgender girlfriend tried to use the ladies restroom, police sources said.

The victim was treated at Bellevue Hospital for his injuries, police said.

Patron was charged with assault, police said.
