The National Organization for Marriage (NOM) has added an ad featuring drag queens Adore Delano and Bianca Del Rio to the list of reasons it is boycotting Starbucks.

Delano and Del Rio competed for the coveted title of “America's next drag superstar” on the sixth season of RuPaul's Drag Race.

In the 60-second spot, developed in partnership with Canadian LGBT network OUTtv and titled Coffee Frenemies, coffee saves the day.

Although the ad has nothing to do with marriage equality, NOM, the nation's most vociferous opponent of allowing gay couples to marry, on Monday attacked the ad in a blog post.

“The pro-same sex marriage corporation behemoth Starbucks has taken its ideologically-driven LGBT agenda to a new level with a new ad featuring two reality TV star drag queens,” the group said.

“Thus Starbucks continues to serve up a healthy dose of ideology added in with the cream and sugar in its cups of coffee. It's as good a reason as ever to Dump Starbucks, if you haven't made the commitment to do so already,” the group added, a reference to its boycott of the coffee giant launched two-and-a-half years ago over its endorsement of marriage equality.

But 31 months later, only 70,000 people have signed NOM's pledge to avoid Starbucks.
