i am going to have to go with the "to sensitive/serious, not commercalised" people. there is that group of people always wanting "Christ back in Christmas" and not "Santa, family and gift day" and now for some Easter is as I call it "egg and bunny day, with candy and gifts". both are being robbed of significance, and it being (i lack some fancy words) . people make silly Easter Bunny movies, people make RomComs that involve Christmas. Ramadan as everone else said cannot be divorced from religious practices.
as for alternitive, I don't think there is anything that can be done, without what others have said, geometic designs, archutecture backgrounds from famous Islamic landmarks...
