everyone seems to be pretty polarized on this but i think no assholes here.

i can see both sides, turkey for christmas is pretty traditional(at least in the us where im from)and it may be what he feels more comfortable with since it’s how he celebrated christmas for years before. or maybe he just likes meat and christmas is more enjoyable for him with a turkey on the table. either way his feelings are valid.

i can also see that tradition is important to you, and honoring your family seems more meaningful to you than it does to him.

however, i don’t see why you can’t make a compromise. you can both respectively have your own meals together, just eat different things. maybe just put some turkey on his plate but put away the actual bird so it’s not out on the table with the rest of the dishes. or you could have a meal with turkey on christmas eve and a meatless meal on christmas!

you’re celebrating the holidays with someone new which means you might be trading in some older traditions for new ones. find a way to compromise so both of you can enjoy the holidays together. best of luck!
