Sometimes multiple things are just true at once. Chanukah is a minor holiday and it’s also an important one. It’s not in the spirit of Chanukah to commercialise it like Christmas and it’s absolutely the best way to assert your Jewishness during the most Christian-centric time of year. You can only really spell Chanukah in Hebrew and you absolutely don’t need to know Hebrew to spell Chanukah/Hanukkah/Chanukkah/etc.
It’s Judaism. Multiple things are true.
