DY: I could hear someone saying that hats are more a political than Halachic symbol nowadays and that wearing them risks of Gaavah. It might not be true, but I don’t think it’s inherently invalid.
sushi: Only if you assume there was an inherent Halachic reason for wearing a hat in the first place. If you assume (like Pashtus in the Mishnah Berurah) that the reason for a hat is because that was what was considered Mechubad at the time, it’s not considered being Mevatel a Minhag to acknowledge that it is no longer considered Mechubad.
