The religious justification for those kinds of head coverings is literally sexist. Women shouldn't show their hair because it sexually excites men when they see it, and it's women's job to be modest to prevent that. That's oppressive. Can somebody associate other, non-oppressive ideas with the garment? I guess, but it's sort of like trying to reappropriate a hate symbol. There's not a lot of point in it, and people will reasonably assume you're a conservative bigot.
