BROOKLYN, N.Y. — The event was billed as “Totally Free” and “Totally Chill(ary),” an unofficial Hillary Clinton campaign party that would feature stand-up comedy, live rap and a pantsuit competition.

The pantsuit contest never happened, and the local rap act failed to show up to the club, a small, out-of-the-way venue in the Bushwick section of Brooklyn.

But for nearly two hours on Saturday night, three days before the New York primaries, a cast of comedians put together by the film maker Heather Fink held up their end of the deal, delivering a free, feminism-themed show for a crowd of mostly female Clinton supporters who were there to celebrate her presidential campaign.

For both the comedians and their audience, the event represented a rare opportunity to express support for Clinton in public without fear of being criticized by friends and family members — or reprimanded by male supporters of Senator Bernie Sanders, known as “Bernie bros,” who have become infamous for lashing out against female Clinton voters on Facebook and Twitter.

“Anytime I post something positive about Hillary on Facebook, people tell me I’m a bad person, they tell me I’m stupid and don’t know anything.”
