“Columbus was not a laudable figure. He was a genocidal figure,” Mazen told WBZ NewsRadio 1030.

Even local Italian Americans voiced support for his measure, Mazen said. He says the holiday should be a day of mourning and that the American education system needs to depict indigenous history more accurately.
