Anti-Trump demonstrators poured into the Upper West Side Monday, filling Columbus Circle and numerous blocks of Central Park West. The "Not My President's Day" rally was the latest in a steady stream of actions against the Trump administration; thousands waved signs, chanted, and navigated a maze of NYPD barricades and roadblocks while organizers shouted out calls for resistance and multiple live bands broke into song.

While the vast majority of Monday's protesters gathered inside the pre-constructed pens along Central Park West, hundreds instead took to the sidewalks outside Trump International Tower—where they clashed head-on with #MAGA-capped opposition. Roughly two dozen Trump supporters counter-protested the rally for hours, and while most of the conflict remained verbal, one woman, upset by the jeers of a man holding a homemade "Latinos 4 Trump" banner, took her own cardboard sign and struck the bill of his red cap. Both sides immediately screamed in uproar.

Howard Beach resident Olga Despinal stood near the Trump supporter crowd holding a sign that read "No Political, Religious, Physical, Sexual Violence." Chavez, a first-generation immigrant from Colombia who closed her own local business in order to join the protest, described her fears of Trump's agenda and campaign tactics.

"When I see 'Latinos for Trump', I feel [his supporters] are misinformed, they don't know who's surrounding Trump," Despinal said. "Because if you really know who Steve Bannon or Stephen Miller are, they are really people who feel that this country should be white. I feel that people who are Muslim, African-American, or Latino and supporting Trump, they don't know what's really going on."

As she stood surrounded by thousands of demonstrators chanting "Black Lives Matter!" on Central Park West and West 64th Street, Dani Chavez, 20, expressed slight disappointment at the rally's stationary, caged-off candor. "I loved when we took over 5th Avenue because that's such an iconic place in New York, so I wish we would have done that," she said. "But people have really great signs and the energy's up. It's important to take back President's Day. No one ever said 'Please' and then got change."

Chavez was wearing a t-shirt with the word "ILLEGAL" screen-printed across the front, and held a sign relating Trump to a man who had sexually assaulted her in the past.

"It's insulting to have a misogynist—and just a blatant asshole—for a president. It's disgusting that we have someone who doesn't believe in female equality representing us."

Back near Trump International Hotel, Despinal had turned away from the Trump-supporter crowd to focus her energy on chanting with fellow protesters. "We're building an America that is going to discriminate and divide us," she said. "I feel very strongly about American values of immigration and diversity, and they're being threatened. I came here from another country and I know many people dream of coming here. How can a Hispanic, whose parents or grandparents came here, hold a sign that says 'BUILD THE WALL'?"
