I think you misunderstood me; I was saying that this would not have been considered such an important/noteworthy case if this had been about political beliefs because they aren’t pandered to in the way that religion is.

Dunno about that. If I saw a political badge on a Dinner Lady, I would just as annoyed as if a woman with a Zorro mask on.
Such deformation of uniform should not be tolerated. It shows a lack of respect for all and only garbage airlines (With therefore no proper maintenance plan) would allow it. So I wouldn’t fly on them.
