Nadler admits he comes on fast and fur-ious when he confronts Canada Goose customers in the video. And he's not the only one to come on strong in the video. Some of the clips were shot by New York City activist Robert Banks.
"He led the Kim Kardashian confrontation and literally stands up for animals every day in NYC," Nadler says "And he doesn't hold back at all."
It's a style inspired by the hard-hitting anti-fur activism of the 1980s and '90s - a movement, he adds, that helped end the inglorious reign of the inglorious full-length fur coat as a fashion staple.
