I never ask anyone in my courtroom to remove their hats. I figure it this way: I would not require an observant Jew or Muslim to remove their hats since the head covering is part of religious expression that harms no one. Therefore, if I tell Juan Gomez or Sally Smith to remove their hats, I am depriving them of their right to dress as they wish solely because their headgear ISN'T religious! My sole test is whether manner of dress and deportment is disruptive. If it isn't, it's none of my business.
France has what I think is an interesting take on this issue. If I understand correctly they have outlawed face covering in public because it discriminates against women, doesn't allow identification, and violates "a certain idea of living together". https://en.wikipedia.org/wiki/French_ban_on_face_covering
