Former Navy SEAL Carl Higbie had a blunt response Thursday to singer Katy Perry’s comments after the Manchester terrorist attack: “go to hell.”

Perry said in an interview Tuesday—the day after the attack on concertgoers leaving an Ariana Grande show in Britain killed 22 people and wounded dozens of others—that people should “just unite and love on each other.”

“I think that the greatest thing we can do is just unite and love on each other and like, no barriers, no borders, like we all need to just co-exist,” Perry added.

Higbie, a vocal Donald Trump supporter, disagreed with Perry during an appearance on Fox News. He said the argument that social segregation of Muslims in Britain produced the Manchester attack was inaccurate because Muslims tend to choose to self-segregate.

“They feel isolated from the community because they isolate themselves… they’ve made no attempt to assimilate to the surrounding population,” Higbie said. “It is unbelievable that they feel that they are isolated because of some external force. No, they are doing it to themselves.”
