Christians aren’t an oppressed minority group or subject of colonization. Christmas is as dominant as ever, it’s not under threat or being attacked in any serious way.

Also, the war on Christmas complaint would have validity if a bunch of people from another dominant culture were trying to take it over and rename it and strip it of everything specifics. Having a broad term “happy holidays” for polite conversation that covers multiple holidays (Hanukkah, Christmas, Kwanzaa, Winter Solstice) is fine and different than specifically taking Christmas and renaming it and doing a massive push everywhere to stop calling it Christmas.
