A bill which would outlaw gay propaganda has been introduced in Russia's lower house of parliament, the AP reported.

The measure reportedly is modeled after a law which took effect earlier this month in St. Petersburg.

St. Petersburg's law criminalizes “public actions aimed at propaganda of pederasty, lesbianism, bisexuality and transgenderism among minors.”

Offenders face a fine of up to $16,500 under the law, effectively outlawing Gay Pride parades and gay rights demonstrations.

Polina Savchenko, director of the St. Petersburg-based gay rights group Coming Out, said the new law would make it illegal to mention the sexuality of famous gay Russians.

“This radical law undermines the great legacy of our city's past and future. If it passes, it would be illegal to mention that famed Russian composer of the 1812 Overture, St. Petersburg native Tchaikovksy, was gay,” said Savchenko. “This law installs a culture of censorship in what was once Russia's most cosmopolitan city and is a huge blow to the freedom of expression in Russia. At a time when people all over the world are opening up and coming out, this law puts Russia back in the closet.”

Supporters introduced the legislation to the State Duma on Thursday.
