"Our 2014 marshals are leaders in brilliant forms of activism through which LGBT people and their allies engage," said Pride March director David Studinski. "Individually, they represent the diversity within the LGBT community and the various struggles our community members have and continue to face. Collectively, their stories reinforce that no voice is too small nor weak to make change in our world - and it starts with being yourself."
