Isn't the NYC Columbus Day Parade a celebration of Italian-American contributions and culture?
Moreover, I don't think you can "Black Out" a specific day of the year for parades/gatherings without running into some pretty serious First Amendment issues.
To say nothing of New York's Dominican population:
https://en.wikipedia.org/wiki/Order_of_Christopher_ColumbusThe Order of Christopher Columbus (Spanish: Orden Heráldica de Cristóbal Colón) is an order of the Dominican Republic. It was established on 21 July 1937. The Head of State confers the order, by advice of the council of the order, both to civilians and military personnel to recognize services.
This order honors the life and works of Christopher Columbus firstly and secondly recognize services to the Dominican Republic or humanitarian services and distinction in the arts and sciences.
If we're going to have Political Correctness, let's talk about the Human Sacrifice conducted by both the Incans, Mayans, and Aztecs:

Huanchaco is a site of the Chimú culture (1200-1400), a predecessor to the mighty Inca Empire, which also carried out child sacrifices.
“This is the biggest site where the remains of sacrificed children have been found,” the excavation’s chief archaeologist, Feren Castillo, told AFP in August. “There isn’t another like it anywhere else in the world.”
Christopher Columbus is a Hero in most of Central and South America to this day. Indeed, as Charles Krauthammer once pointed out, Hispanic America is Columbus's legacy.
Columbus was who he was. I'm not unmindful of his faults, and he was, arguably, something of a grifter at points in his life. This hardly makes him unique in history. I'm not an apologist for the Conquistadors, but let's stop making Indigenous Peoples something they were not, and recognize Columbus's role in history, and what it led to, good and bad. And, while we're at it, let's remind Howard Zinn that he's anti-American on a number of levels, while we resist the rewriting of American History to reflect the anti-American sentiments of Zinn and Company.
