The protesters gathered on the sidewalk in front of the 61-year-old actor's home to voice their opinion after Neeson showed his support to the city's horse-drawn carriage industry, reported New York Times.
The activists brought some signs which read, "Liam Neeson: Stop Supporting Cruelty!" and "Worked to Death!" with a photo of a dead horse. One of the activists, Peter Wood, explained his view to the news outlet, "It's 2014, not 1914. It's time for a change."
"Horses don't belong in traffic, surrounded by buses," Wood, who lives in Manhattan, continued. "They don't belong in the city; it's outdated, it's cruel. Life attached to a carriage with a poop bag attached to your rear end - that's no life."
Neeson, however, argued that the horse were not mistreated. "It has been my experience, always, that horses, much like humans, are at their happiest and healthiest when working," he said, calling the horse-drawn carriage "humane industry that is well regulated by New York City's Departments of Health and Mental Hygiene and Consumer Affairs.
