The Australian Greens are calling on Family First Senator Bob Day to condemn the vicious anti-gay rhetoric printed in 100,000 pamphlets supporting his re-election.
According to the Advertiser, Senator Day is being supported by a group who regard gay people as "detestable," along with anyone who has sex outside of marriage.
"These views are extreme, deeply offensive and totally at odds with the views of the South Australian mainstream," Greens sexuality spokesperson Senator Robert Simms said.
"Senator Day says he wants to put Families First, what about LGBTI people and their families and friends? Senator Day must condemn this offensive organisation and distance himself from this ugly hate speech."
South Australians face a stark choice on Saturday, between the Greens and Family First for the final senate seat.
"The Greens will always fight against homophobia and stand up for fairness and equality. The choice couldn't be starker," Senator Simms said.
