A bill that oppresses gay people through gay pride fines and bans giving children information about homosexuality won approval in a landslide vote in Russia's lower house of parliament. Two dozen demonstrators were detained for protesting the bill.

While parliament debated the bill, gay rights activists held a "kissing rally" outside the State Duma in central Moscow. According to The Associated Press, the activists were attacked by hundreds of Orthodox Christian activists and members of pro-Kremlin youth groups. The brawny young men threw eggs at the activists, shouting homophobic obscenities at them.

Riot police arrived at the scene and detained more than two dozen protestors. Most of them were gay rights activists. Some were beaten by masked men on another central street, across from the Red Square.

The law, which passed 436-0, bans the spreading of "propaganda for non-traditional sexual relations" to minors and sets heavy fines for violations. One deputy abstained and no one voted against.

The bill can fine individuals up to 5,000 rubles ($156) and companies (including media outlets) up to 1 million rubles ($31,000), for telling minors about the LGBT community and participating in any gay activities, The Christian Science Monitor reports. Foreign citizens helping to organize gay pride events can be deported or jailed for up to 15 days and then deported.

The Associated Press reports that the bill is an attempt to promote traditional Russian values in the face of Western liberalism, which the Kremlin and the Russian Orthodox Church see as corrupting Russian youth and contributing to the protests against Putin's rule.

Lawmakers have accused gays of decreasing Russia's already low birth rates. They even went so far as to say that homosexuals should be barred from government jobs, undergo forced medical treatment or exiled.

On Tuesday, many anti-gay activists rallied outside the Duma. One activist held a poster that read: "Lawmakers, protect the people from perverts!" while others held Orthodox icons and chanted prayers.

Amnesty International condemned the bill: "[The bill represents] a sorry attempt by the government to bolster its popularity by pandering to the most reactionary elements of Russian society - at the expense of fundamental rights and the expression of individual identities," John Dalhuisen, the human rights group's Europe and Central Asia program director, said in a statement.
