The Pearl Jam frontman had some choice words, calling Butker at “f—kin’ p—y” during a May 18 concert in Las Vegas.

“That’s some good men, good women, making up a great band,” he said, gesturing to his fellow musicians onstage. “The singer, Jessica [Dobson], and the keyboard player, Patti [King], they must not have believed that [deepening his voice] ‘diabolical lie’ that women should take pride in taking a back seat to their man.”

Vedder—dad to daughters Olivia and Harper with wife Jill McCormick—waited for the applause to trail off, then added that homemaking “is maybe one of the hardest jobs” and one to “definitely take pride in.”

But he didn’t “understand the logic” of advising anyone, men or women, that they’ll benefit from giving up their dreams.

And, Vedder added, “There’s nothing more masculine than a strong man supporting a strong woman and people of quality do not fear equality.”
