I realize this probably won't change anything given what you've said, but I felt compelled to reply.

I do not think banning something because it has queer representation or something similar is a good idea. I haven't watched that show, so I cannot comment on it in particular, but if all it was doing was going "here are these queer people living normal lives like everyone else," then there's no real harm. All banning stuff like ylthat really does is cement in your child's head that these people are weird and abnormal when she finds out they exist (especially if she asks your wife, it sounds like). Importantly, hiding stuff from your kids isn't gonna stop them from learning about it, they'll learn through alternate sources eventually.

Anecdotally, my conservative parents did something similar with my younger brother. They banned certain children's networks on TV when he was growing because they didn't like the content. Well, he eventually got unfettered access to YouTube and the internet as a whole and is now a fascist (self-described). Presumably the only reason he isn't virulently anti-LGBTQ+ is because I am LGBTQ+. I, on the other hand, had to research practically everything myself because I felt like I had no one I could talk to given my parents' views (especially given some of the horror stories on the internet). Note that I grew up when LGBTQ+ representation in children's shows was pretty much nonexistent or super minor still.
