Communist can do what they like, I can’t stop them.
Personally though, I’m not keen on taking a character whose whole artistic purpose is to be a cute little pilgrim and turn her into something she isn’t or emphasizes something that runs contrary to that purpose.

I realize I’m being about it, but I think too much of the fan art I’ve seen has strayed from the purity and innocence the original artwork was meant to invoke.
Whether it’s people overly memeifying it, or weird trads portraying her as a crusader killing people etc. and so on.

Sure, she’s not high art or even I would say sacred, but people are taking a character who was made to help guide people to God and have foisted a lot of their own earthly hang ups on to it and that rubs me the wrong way.

Sure the Pope says Catholics and Marxist should be more open to working together, but I don’t know if you can build that kind of relationship by taking a “Catholic symbol” removing everything holy about it and replacing it with communism.
It strikes me as rather disrespectful and or offensive and thus counter-productive to that goal.
