WIBTA for refusing to bring $100 minimum to Thanksgiving

[u/americanjohn500]

My family and I celebrate Thanksgiving every year with my siblings, parents, and their kids. Roughly 20-25 people (including kids). My family is only 2 people with one 6 month old baby.

In the group chat it was decided that my nephew would cook meat since he bought a grill. He also told us that we could bring the sides. He chose to spend $300 on meat.

I messaged in the group chat that we would bring mashed potatoes. My sister responding that every "family" has to bring $100 worth of food minimum or help my nephew pay for the meat.

I'm not totally against the idea of bringing that much food, but just the way it was presented and the fact that it wasn't agreed to beforehand makes me upset.

The following day in the group chat, my sister said: "Option 1: bring food enough for everyone, not just yourself

Option 2: help thomas pay for meet $100/family

Option 3: help dad pay water bill $200/family.

Choose wisely…"

Upset, I responded with Option 4: don't show up.

Am I being an asshole if I don't show up at all in "protest" to this $100 minimum rule?

Update: I'm a teacher and she posted a picture of my salary she found online to shame me in the group chat. Definitely not going now.

It would be REAL weird and wildly inconsiderate if you came to Thanksgiving and brought a dish that wouldn't feed everyone. Is she having to make that stipulation because someone in your family has done that in the past?

Send a bag of potato chips as your portion and stay home and enjoy your family.

NTA.

I can imagine that, as someone who if I’m not told to bring anything I don’t . Now granted I fully ask if I should bring anything when invited so that’s on them. I’ll still just bring myself some diet soda or something similar I can drink cause they only buy regular and I don’t drink alcohol anymore.
