I know so many people who dislike or dread Christmas for very valid reasons: bereavement, lack of family, lack of money, unhappy memories and associations. Yet every year when posters express disquiet about being bombarded with Christmas from October on they are called grinches or miseries or fun sponges or ordered to just ignore all the music, decorations etc.
None of these people are asking for Christmas to be cancelled or for December to become a Christmas free zone. They are simply asking if the Christmas season could return to it's origins as a December celebration/religious feast, and not take over a quarter of the year.
AIBU to ask people to stop for a minute and remember that some people find Christmas very difficult and don't want it in their faces the minute Hallowe'en is over?
