Yeah, all this extremist fundie crap just makes the product they're against even more enticing, which is the exact opposite effect of what these idiots (which is what they really are) truly want in the end. What they're doing only pushes people away from religion, not into it, unless it's by wrongful force, which is never good for any side of the argument, especially their own.
A Catholic (Dana Terrace) making a cartoon about witches and demons is about as big a deal as a Christian (J.K. Rowling) making a book about wizards secretly living among humans - in that it isn't really such (nor should it be seen as such.), honestly. What really matters is if these things are actually fun and entertaining to watch; these fundies are just looking for something to complain about, because no one wants their brand of "religious help" forced on them anytime soon, or hopefully anymore, in this case. No one who's actually smart, anyway.
Hell, you could say the same about water being wet and full of fucking chemicals, which is an actual thing people like this should be fighting against and encouraging others to do the same - as in, some actual good in the world for once, instead of whining about how people, especially easily impressionable beings, which children are (and we all were such in our pasts) need to be forced to do this and that "for God".
Furthermore, I'm wondering where these idiots were at when Star Vs. Was still a thing... You know, the girl who wears devil horns (her signature headband) on her head everywhere she goes, that is.....
