The US clothing retailer GAP has released a new advertising campaign in Los Angeles, which features a gay couple embracing under one t-shirt, and has predictably drawn the wrath of the anti-gay group, One Million Moms.

The billboard which features the photo reads: “Be Bright, Be One.”

One Million Moms, which has previously targeted JCPenny and Urban Outfitters for their pro-gay ads, has been quick to condemn the ad, and has called on its members and supporters to boycott GAP and its subsidiaries, including Old Navy, Banana Republic, Piperlime and Athleta.

These brands, a letter posted on their website claims, “does not [sic] deserve, nor will it get, money from conservative families across the country.”

The letter adds: “Supporting GAP is not an option until they decide to remain neutral in the culture war. GAP needs to seriously consider how their immoral advertising affect the youth of our nation.”

“Christians should urge for the removal of GAP’s offensive billboard in Los Angeles and any other city where it is located,” the letter continues. “GAP will also need to cancel any plans to use the “Be One” ad campaign elsewhere including store-front posters, its website, and in print magazine ads.”

GAP has yet to comment on these threats.
