Vitriolic anti-gay ads and brochures have popped up in a number of Australian cities ahead of the nation’s same-sex marriage vote, angering LGBTQ rights advocates and lawmakers. Snapshots of the ads have emerged on social media in recent days. The most troubling image was reportedly spotted in Melbourne, depicting two men set to attack a small child with rainbow-colored belts. “Stop the fags,” the ad reads.

Meanwhile, a bilingual brochure aimed at English and Chinese-speaking Australians that blasted homosexuality as “a tragedy of a family” and a “curse of death in terminating the family line” was apparently distributed in the Sydney suburb of Hurstville.

It’s unclear who produced the ads or where they came from, but they’ve nonetheless succeeded in making international headlines and drawing near-universal condemnation from Aussies on both sides of the debate. Among those angered by the campaigns was Victorian Human Rights Commissioner Kristen Hilton, who called the poster and pamphlet “a really disturbing trend.” “I think that people need to call that out and condemn this type of material,” Hilton told the Australian Broadcasting Corporation. “Yes, people are entitled to have different views, but in a debate like this it’s really important to convey those views respectfully.” Echoing those sentiments was Australia’s Parents and Friends of Lesbians and Gays spokeswoman Shelley Argent, who called the poster “pretty distressing” in an interview with ABC. The Australian Christian Lobby’s managing director, Lyle Shelton, who has been a vocal opponent of same-sex marriage, said on Twitter that he was “happy to condemn” the controversial effort.

Hey @Rob_Stott you know us well enough to know we would never do something like this. https://t.co/pD59LyNnGf — Lyle Shelton (@LyleShelton) August 21, 2017

Absolutely Rob. Some things go without saying but I’m happy to condemn. We’re on a unity ticket. https://t.co/XqU408Oebh — Lyle Shelton (@LyleShelton) August 21, 2017
