The Vice Media co-founder was invited to speak to NYU's College Republicans at the school's Kimmel Center on Washington Square South near Thompson street.
"If he doesn't respect people's lives, we don't need to respect his words", one protester, who identified herself only as Leah, said of McInnes.
The New York City Police Department said 11 people were arrested outside New York University on Thursday during a protest against conservative comedian Gavin McInnes.
Those arrested face charges including drug possession, criminal mischief, disorderly conduct and obstructing government administration, police said.
Beckman says McInnes tried to continue but stopped when protesters rushed into the room.
Gizmodo reported that McInnes barely made it into the NYU building.
Hudson's Bay Looking To Take Over Macy's
Ahead of this latest rumor, Macy's market capitalization was almost $10 billion, while Hudson's Bay was about $1.7 billion. But now, things could be changing, because Macy's stock surged more than five percent on Thursday.
"Whose campus? Our campus", the protesters chanted.
A photo uploaded to Twitter showed a "Make America Great Again" burning in front of the building.
The protest was organized by a group called NYU Anti-Fascists, who say McInnes is known for using "incendiary language".
The protests were apparently coordinated through Facebook under the name "Disrupt Gavin McInnes at NYU". When NYC Antifa began to share information about members of the group with their employers (in many cases leading to job loss), McInnes urged the Proud Boys to attend an Antifa concert and "wreck the shit" of the "f*ggots".
NY police officers stepped in to form a barrier between the protesters and McInnes supporters.
The New York clashes came a day after students at the University of California Berkeley similarly sought to block the campus appearance by Breitbart News editor Milo Yiannopoulos.
