Kim Kardashian has spoken out in opposition to the California Supreme Court’s decision to uphold the state’s ban on gay marriage.

The buxom brunette says she is dishearted that the high court refused to do away with Proposition 8, which denies same-sex couples the right to wed.

“I thought we were more forward thinking than this, and I’m disappointed in the Supreme Court for being so close-minded,” the star of E!’s Keeping Up With The Kardashians wrote on her Official Blog Tuesday. “Everyone… gay, straight, bisexual, transgendered – everyone should have equal rights to marry who they want to.”

“I have many gay friends, and all I want is for them to be happy, yet this is just another obstacle in their way.”

She added: “Now they must continue fighting to be granted a basic civil right that many people take for granted. Shame on you, California! We must all continue to fight the hate!”
