Christians and Muslims have joined up in Singapore in an effort to protest against a gay rights rally which last year attracted over 20,000 people.

Despite political gatherings needing a permit, regardless of how many people are to attend, the Pink Dot rally in 2013 attracted more than 21,000 people just months before the High Court rejected a challenge to the country’s sodomy law.

Now Ustaz Noor Deros, a Muslim teacher, has launched the WearWhite campaign, which urged muslims to reject the Pink Dot event, and to wear white to pray on the night of the event.

“The movement’s genesis was from our observations of the growing normalization of LGBT (lesbian, gay, bisexual and transgender) in Singapore,” reads the WearWhite website.

The Facebook page of the campaign has over 3,000 likes, and contains a message in pink on its cover page reading “Return to Fitrah”, meaning innocence or nature.

The campaign has now been joined by Jawrence Khong, the head of the Faith Community Baptist Church, and the LoveSingapore network of churches.

“We cannot and will not endorse homosexuality. We will continue to resist any public promotion of homosexuality as an alternative lifestyle,” Khong said in a Facebook post.
