On Saturday afternoon, dozens of people made up of far-right activists, Trump supporters, and free speech advocates took to the streets in Boston for a so-called “straight pride” parade. The mostly male group attracted a large amount of protesters—and a mocking tweet from Rep. Alexandria Ocasio-Cortez (D-N.Y.).

“For men who are allegedly so ‘proud’ of being straight, they seem to show real incompetence at attracting women to their event,” Ocasio-Cortez tweeted. “Seems more like a ‘I-Struggle-With-Masculinity’ parade to me.”

The marchers carried “straight lives matter” signs as well as American flags and pro-Trump signs.

The organizers of the parade, titled Super Happy Fun America, said the point of the parade was to raise awareness of the alleged issues facing the straight community and poke fun of pride parades that are held around the world in support of the LGBTQ community. But according to a Buzzfeed report, the organizing group has ties to white nationalist groups.

Protesters clashed with marchers and Boston police reported that 34 arrests had been made and the city’s EMS spokesperson said nine people had been taken to the hospital. Ocasio-Cortez followed up her tweet with a call to contribute to the bail fund for the activists who’d been arrested while protesting.
