I disagree with the meme, simply because the Simpsons are the more endearing choice here, I think. Flanders was always this weird religious and hyperprotectic guy.
Flanders is especially bad in this episode. Trying to baptize your next-door neighbors' (or anyone's) kids without their consent is fucked up and a reason to bar the Flanderses from ever fostering children again.
I mean, if you're going to overthink a meme, at least get it right within the repurposed context. She technically went third party when Marge showed up. Obviously, that wasn't the intended meaning of this shitpost, as I would've included that frame if it were, but hey, you wanted to nitpick.
