After facing criticism over their polygamist lifestyle, the stars of TLC���s Sister Wives are speaking out in favor of gay marriage.

“I actually believe the state should never be involved in marriage,” patriarch Kody Brown, who has four wives and 16 children, exclusively tells In Touch. “That is a religious choice, or it is a personal choice. It should not be something that the state is dictating.”

His wives — legal wife Meri, plus Janelle, Christine and Robyn — agree. “Every adult should have the right to marry and love who they want,” says Janelle. Adds Meri, “We try to teach our kids: Don’t judge other people.”

The Browns’ stance on the hot-button issue comes on the heels of a Utah police investigation of the family for a possible charge of felony bigamy. “There were no charges filed,” says Kody. “Case closed.”
