Brooklyn’s Eastern Parkway will buzz with steel drums and flag-draped floats on Monday during the West Indian Day Parade. But Haitians are marching under more solemn circumstances this year. Federal immigration enforcement has intensified, and Haitians have lost temporary protected status. It has affected hundreds of thousands. Organizers say the parade is a defiant assertion of pride amid a traumatic year. One organizer says the parade is a rare bright spot. Her group continues to participate regardless of the challenges. It will showcase resilience through music, dance and art. The parade highlights Haitian history, culture and community strength.
