Pop star Adam Lambert is unhappy with One Million Moms, a socially-conservative activist group that is urging a boycott of retailer JCPenney, which recently ran this advertisement featuring a same-sex couple:

According to Time.com,

The Father’s Day ad shows real-life dads Todd Koch and Cooper Smith playing with their children, Claire and Mason.

The ad reads: “First Pals: What makes Dad so cool? He’s the swim coach, tent maker, best friend, bike fixer and hug giver — all rolled into one. Or two.”

One Million Moms, part of the American Family Association, complained that JCPenney was “continuing on the same path of promoting sin” with this new ad, and recommended their supporters write “REFUSED…RETURN TO SENDER” on their JCPenney catalog when it arrives. They also recommend members close their JCPenney accounts and talk to their local store manager about their concerns.

Lambert, who is openly gay, has been an outspoken supporter of social acceptance of lesbian, gay, and bisexual people.
