A Christian conservative group is threatening to boycott Nickelodeon over gay characters in the Nicktoon The Loud House.

Howard and Harold McBride, voiced by comedian Michael McDonald and TV personality Wayne Brady, respectively, are the first same-sex couple to be featured in a Nickelodeon animated series.

They are the married parents of Clyde McBride (Caleel Harris), the best friend of Lincoln Loud (voiced by Sean Ryan Fox in the pilot, Grant Palmer in subsequent episodes), the show's star. Loud, 11, is growing up with 10 sisters.

Monica Cole of One Million Moms called on her supporters to contact Nickelodeon and urge the network to remove the characters from the show.

“If producers keep this episode as originally planned, then conservative families will have no choice but to no longer watch Nickelodeon in their homes so they can avoid the previews, commercials and reruns for this irresponsible episode,” Cole told the group's members. “Tell them you are prepared to join thousands of other voices in urging advertisers to place it on their 'do not advertise' list for introducing children to LGBT content.”

Cole accused Nickelodeon of pushing an agenda. “Networks, even children networks, are attempting to desensitize children and families in general,” she told One News Now. “This is just proof that Nickelodeon [has] decided to be politically correct instead of just providing clean, family-friendly programming.”
