Or telling someone “happy birthday “ when they’re in a group of people who aren’t having birthdays themselves. Only a three year old would get upset that they’re not included.
Back in the day, Christians would build churches on ground that was holy to other religions, and invent Christian holidays on the same day. So imagine you’re a mediaeval pagan, it’s time to celebrate the solstice, and you go to the sacred grove where the local goddess likes to hang out. And the trees of the sacred grove have all been cut down and used to build a church in their place, and the Christians welcome you in and say “merry Christmas”. Well, it’s still the only way to pay respect to the goddess, so you go in, and you do your traditional ceremonies, and you bring your kids so they can learn the traditions. And ten years later your kids are celebrating Christmas and they’ve forgotten all about their own culture.
That’s why Christmas was invented. Christmas was invented so you could say Merry Christmas to other religions and steal their heritage.
