I can understand if you didn't want to go to X-mas church services but you don't want gifts? To me X-mas is all about getting together with the people you like/are related to, and giving each other gifts to show your appreciation - or because you know they're going to get you something and you're going to look like a dick if you don't reciprocate. Ah, the joys of the holiday season. I don't see anything other than a passing relation to religion in the giving and receiving of gifts.

Unless they're labelled "To Reefer Rogue from Little Baby Jesus Who Was Born On This Day" I'd take 'em, although you're free to potentially offend people and pass up free swag if you want.
