Activists in Botswana are calling on the government to bar Pastor Steven Anderson from entering the country.

More than 2,300 people have signed a petition calling on the government to deny entry to Anderson, who ministers at the Faithful Word Baptist Church in Tempe, Arizona.

“By calling for the killing of gay people, Pastor Anderson's messages are homophobic and condone violence against fellow human beings and a group that is already marginalized,” reads the petition.

Anderson gained national headlines in 2014 when he posted video of a sermon he gave in which he claimed to have discovered “the cure for AIDS.”

“[W]e can have an AIDS-free world by Christmas,” he said. “Because if you execute the homos like God recommends, you wouldn't have all this AIDS running rampant.”

More recently, Anderson cheered the June mass shooting in an Orlando gay nightclub that left 49 people dead and wounded dozens.

South Africa, which borders Botswana, announced earlier this week that Anderson would not be allowed to attend a “soul-winning marathon” being held by a local church in Johannesburg. The government said that it acted because Anderson and members of his church promote hate speech and “social violence.”

According to Anderson's Facebook page, he arrived in Botswana on Thursday. But other reports indicate a September 23 arrival.
