<human>: Can you give me a shortened version of the text?

My family have know I don't believe in any religion for years. Yet I still come around and celebrate Christmas with them as a traditional thing.

I've got a few threaten from some family members over years. They would tell me I shouldn't even be around or next year they shouldn't acknowledge I exist. Usually they try to say it in joking manner. 

Today my aunt totally exploded and yell at me about how I shouldn't have any part in Christmas unless I do it in Christ's name. 

This piss me off! I was suppose to go down there and introduce my girlfriend (who also don't believe in any religion) to the family. I want to tell her "Guess you want to lost an nephew this year too" (My sister passed away few months ago)

But don't know if this would be a good idea...
<bot>: Aunt got upset because I made it known I don't celebrate Christmas for religion reason. She chewed me out over it.
