Hundreds gathered to fight against hate at Adam Yauch Park in Brooklyn, N.Y., on Sunday (Nov. 19). This after vandals defaced the playground with anti-semitic graffiti and scrawled “Go Trump.” Since then, the equipment has been repainted with a colorful design of flowers.

The memorial park was created in memory of the late Beastie Boys member Adam “MCA” Yauch who passed away from cancer in 2012.

Adam “Ad-Rock” Horovitz appeared at the Anti-Hate rally and gave a powerful message to the passionate crowd. The veteran rapper reflected said that MCA always encouraged a non-violent way of life and he urged fans to follow in those same footsteps.

"Spray painting swastikas in a children’s playground is a messed-up thing to do," he told the crowd. "And for many of us, it has special meaning, because this park is named for Adam Yauch, who was my friend and bandmate for over 30 years."

"But he was also someone who taught non-violence in his music, in his life - to all of us, and to me. But this is more about someone in our community linking Nazi Germany to Donald Trump in a ‘hell yeah’ kind of way in a park where children play," he continued.

Horovitz also reportedly said, “Keep your eyes open, stand up for each other. This is homegrown terrorism for real... I reject Donald Trump's vision for America. New York City, I'm asking you to do the same.”
