() The X account for Dropkick Murphys, a Massachusetts-based Celtic punk rock band, was suspended Monday night after the band’s frontman called out an audience member wearing a “Make America Great Again” hat.

“If you’re in a room full of people and you want to know who’s in a cult, how do you know who’s in a cult? They’ve been holding up a f–king hat the whole night to represent a president,” lead singer Ken Casey said Monday, according to videos posted by attendees.

The “I’m Shipping Up to Boston” singer called the audience member’s black-on-black MAGA hat the “Elon Musk True Nazi edition,” as it’s the style the X owner is frequently seen wearing.

Musk, a top Trump administration adviser, faced backlash in January for giving what some interpreted as a Nazi salute during an event following President Donald Trump’s inauguration.

Casey then echoed a familiar anti-Trump sentiment: “This is America. There’s no kings here!”

Following the St. Patrick’s Day concert at Boston’s Fenway Park stadium, the band’s X account was suspended. Visiting their page brings up a message that reads, “X suspends accounts which violate the X Rules.”

It is not yet clear what rule the band violated. has reached out to X for clarity on the band’s suspension but has not yet heard back.

According to USA Today reporting, Casey called out another fan in a MAGA hat during the band’s March 8 show in Clearwater, Florida.

In Florida, Casey said, “We don’t care if we lose fans because when history is said and done, we want it known that the Dropkick Murphys stood with the people. We stood with the workers.”

In 2022, the band’s attorneys sent a cease-and-desist to a neo-Nazi group using the song “The Boys Are Back” in a tweet, according to the Associated Press.

Dropkick Murphys also called members of the Nationalist Social Club-131, a white nationalist group, “losers” for their appearance at that year’s South Boston St. Patrick’s Day parade with “Keep Boston Irish” signs.
