I know that most people enjoy Christmas, Easter etc with no regard for the actual Christian basis and meaning of the celebration, but aibu to think that those people should then not get all offended by the religious aspects and sometimes be downright rude about it?? The nativity play, spreading the word of god through carol singing etc..... Dare I mention operation Christmas child?! If you enjoy Christmas then at least try to accept it is actually about the birth of Christ or at least respect that others will celebrate this fact and may try to share that with those around them with the best intentions.
Basically cheer up, be accepting, be kind.
