I mean I'll go a step beyond that, I don't have context for who this is or where it was posted but I doubt the person getting this is actually fash. They're probably just a big HP nerd who liked the logo. I've definitely consumed fictional media where there's some evil faction that none the less had really cool iconography, cool enough I'd maybe get like a bumper sticker or something of it. I was in a DnD game once with a bunch of art students and one of them made a real cool logo for the evil cult we were at war with and a couple of us ordered custom dice bags with the graphic on it, but none of us condoned the act of trying to summon a extra-dimensional demon to destroy the world.

This only really seems weird cuz HP is such a popular and politically charged work of fiction, if someone did this for a more obscure work of fantasy I probably wouldn't bat an eye at it.
