MAGA, for instance, was memetic, so if you use/repurpose it, there's a relatively unambiguous origin. Deus Vult in this context, not so much; it lacks the spread and saturation necessary. If the Swastika was only present on a small subset of Nazi paraphernalia, it wouldn't be nearly as taboo - it's till so toxic today because it was on everything and so readily associated.

So I don't really think that argument applies here.
