Navigating the holidays with family

I'm looking for advice bur sorry if this turns a little rant-y.

I (30 MTF) came out to my family recently, as I have begun taking hormones and medically transitioning and didn't want to hide it anymore etc. I come from a very large, Catholic family (8 kids + my parents, yeesh).

My parents did not take my coming out well. While they respect I'm an adult who will make their own decisions, they feel I'm making the wrong decision. They will not address me by my chosen name, pronouns. I'm still welcome in their home but they refuse on trying to see me as anything else but their "son" (It is not part of "God's plan", "transgender ideology" is evil, I should just be medicated and evaluated by a Christian psych instead of my own, etc etc).

Most of my siblings, though, are all OK about my identity. While half are still devoutly religious, they don't see any reason why their faith should stop them from supporting me like our parents are claiming. Even the most religious of my siblings says "that mom and dad are being ridiculous. They can still support their kid. That's what God literally wants them to do."

So with that context, the holidays are coming up. ALL of us will be in the same house for the first time in a long time, and for the first time since I've come out. Many of my siblings are asking me whether they still need to call me my deadname out of respect for our parents (since it's their home) or if I want them to call me my chosen name. Obvs I want them to call me my chosen name but some have raised the point that this will probably cause a meltdown for my parents and we should just have a drama-free Christmas.

I feel like I'm losing my mind because WHY does "drama-free" mean that I have to be uncomfortable and hide myself, even after I made the Very Big Move to come out to them. Am I being unreasonable here!? Should I just silence myself even though literally everyone else (even my siblings' partners) are fine with this. It's literally just our parents who have an issue. Some of the siblings think I should not make a fuss, even though these same siblings say that they're okay with me being a trans woman. It's like none of them are brave enough to stand up to our parents and it's very silly cause we're all literally adults.

TLDR; should I not go by my pronouns or chosen name this holiday season, since we will all be gathering at my parents' home and it would be "disrespectful" (I cannot roll my eyes enough).
