Clifford the Big Red Dog has delighted children on television and in books since 1963, but an organization that’s an offshoot of the anti-LGBTQ hate group the American Family Association is not delighted by a recent change in the cartoon series.

The organization, One Million Moms (which incidentally, does not have one million members) is not happy that one character, Samantha “has two mommies,” LGBTQNation reports. And One Million Moms (1MM) is upset that viewers weren’t warned about the relationship. So it issued an action alert.

“There was no disclaimer at the beginning of the episode where their relationship is explained,” wrote the group’s leader, Monica Cole, in the alert.

This isn’t the first time the group has targeted children’s programs that feature same-sex relationships, having attacked such PBS shows as Arthur and Sesame Street for including LGBT people. The group specifically pointed to the Sesame Street episode that featured theater performer Billy Porter, and Cole complained:

“And if a same-sex wedding and a same-sex relationship in children’s programming weren’t enough, PBS recently announced that Sesame Street will feature a drag queen activist wearing a gender-bender tuxedo-gown in one of its episodes this year. Sesame Street posted on its’ Facebook page: ‘Bill Porter bringing those fierce vibes to Sesame Street. #Season51.’ The post also included a fire emoji which is used to signify that something is cool, awesome, or exciting, or ‘on fire.’ It can also imply that someone is sexy or hot.”

“Discussion of such controversial topics and lifestyle choices should be left up to parents,” Cole wrote. “PBS KIDS should not introduce the LGBTQ lifestyle to young children. PBS kids should stick to entertaining and providing family-friendly programming, instead of pushing an agenda.”

The organization has even filed a petition about this. You can view it here.
