how dare we speak merry christmas

But that's a very important part of the holiday spirit! "Merry Christmas" is the greeting we say when we're wishing someone a happy Christmas season, and it's also the phrase that we say when we're spreading the spirit of Christmas around. It's a sign of goodwill and friendship, and it's a way of spreading joy and happiness during the holiday season. So why don't you think that's a good thing?
