To the long list of Russians whom President Vladimir Putin is persecuting, add gay people and those who support gay rights. Along with political dissidents, journalists and billionaire businessmen, they are increasingly the focus of repellent laws and repressive practices that could send them, and anyone who dares defend them, to jail.

For some time, antigay sentiment has been spreading in Russia’s conservative society, encouraged by the Kremlin and the Russian Orthodox Church. But Mr. Putin and his government have taken that to a new level by legitimizing the hatemongering in legislation.

Earlier this month, he signed a law banning the adoption of Russian-born children to gay couples and to any couple or single parent living in any country where marriage equality exists. Last month, Mr. Putin signed a law allowing the police to arrest tourists and foreigners suspected of being gay or pro-gay and detain them for up to 14 days. He also signed a bill classifying “homosexual” propaganda as pornography with vague wording that could subject anyone arguing for tolerance or educating children about homosexuality to arrest and fines.

There is no defense for such actions, which occur against a backdrop of growing violence against gays and could be seen as a license for even more violence. Russia is in danger of moving from pursuing the rule of law to the rule of hate. The new laws contravene Russian commitments to human rights and fundamental freedoms under the International Covenant on Civil and Political Rights and Organization for Security and Cooperation in Europe.
