Is it wrong to wear a hijab that is green and red around Christmas time??? 10 points?

Admittedly, it's towing the line. Some people will be ok with it since you don't believe. Others will NOT be ok with it because you're showing acceptance to a false or changed religion. The Trinity is not an ideal to show affection for. Your act could be seen as reinforcing the Christian belief in them, which is a big no-no. If you like, maybe just wear something generic. A black cap or another colour with a snowfake pin? That's what I did. That's more festive for Winter than an affiliation with a holiday.
