A chain of Russian food stores has posted signs in its windows saying it refuses to serve LGBT customers.

The shops are owned by German Sterligov, a devoutly religious millionaire who has participated in several unsuccessful political campaigns, including a run for the Russian presidency in 2004.

Though Sterligov made most of his money by opening a mercantile exchange shortly before the fall of the Soviet Union in 1993, he's since abandoned the financial world in favor of a renewed devotion to the Russian Orthodox church and organic food produce.

It was at one of his organic food shops in central Moscow that a sign reading “No entry for faggots" was first noticed.

"Our planet is full of filth and sick humans," Sterligov told Reuters at a country fair outside the capital city. "In front of our eyes is the historical experience of Sodom and Gomorrah when God burned these towns."

At the fair, the 50-year-old businessman also praised President Trump for revoking former President Obama's declaration that public schools should allow transgender students to use the bathroom of their choice.

"We thank him. May God give him health," Sterligov said of Trump.

Yulia Gorbunova, a Human Rights Watch researcher, said the retail chain's sign sends a terrifying message in a country where homophobia is already so prevalent.

"It seems like they are promoting homophobia in an already homophobic society and it only leads to rising tensions," she explained. "The state certainly has a responsibility to stop that and step in."

Earlier this month, Russian president Vladimir Putin—who regularly denies discriminating against sexual minorities—approved an investigation into the allegations of an anti-gay purge in Chechnya.

Though experts unsurprisingly found nothing of concern in the region, LGBT Russian activists are continuing to fight for their Chechen neighbors.
