Rocker Thurston Moore has blasted a female blogger for "gender fascism" after she criticised the former Sonic Youth frontman for discussing the affair which ended his marriage to his bandmate Kim Gordon.

The veteran musician recently opened up about finding love with book editor Eva Prinz in an interview with British magazine The Fly, admitting they are now living together in London following his split from Gordon in 2011.

He said, "I'm in a really romantic place with Eva; we've kinda been a couple for close to six years. A lot of those years nobody was very aware of it except us. The cat's been out of the bag a while now...

"I've had some life issues. In your 40s and 50s things can change in ways that upset the order of things that have been established over 25 years-plus of marriage. It's really distressing. You have to work through it... (but) I'm involved in a really sweet relationship and it really does make me happy, it truly does."

His candid comments prompted one Jezebel.com blogger to brand Moore a "d**k" for gushing about the woman he cheated with, but the rocker has since hit back to defend himself.

In an angry post on Facebook.com, he writes, "Jezebel is gender fascism. By not having any real critical facility to understand, in their case, men in relationship to women (presumably them) they opt to promote hate by imperialist blather. By couching it in feminism is a distinct lack of class, but i'm sure they're having a bit of online fun and when they grow up maybe they'll glean the complexities of real life and love."
