At a performance Thursday in Moscow, out singer Rufus Wainwright condemned a Russian law which prohibits the promotion of “gay propaganda” to minors.

According to The Moscow Times, Wainwright said the law was offensive because “it's really young gay people who are 18 who need our help, and need to learn and feel loved and accepted. To cut them out is a terrible crime.”

He dedicated his song The Gay Messiah to composer Pyotr Tchaikovsky, which he described as his “favorite gay Russian.”

Young people under 18 were not allowed to attend the concert at Dom Muzyki.

The audience applauded when Wainwright said “I'm gay” and called the law “disgusting.” (The video is embedded on this page. Visit our video library for more videos.)

Wainwright and longtime partner Jorn Weisbrodt married two years ago in New York. The couple has one daughter, Viva Katherine Wainwright Cohen.
