Posting from a throwaway since I use my regular account on craft subs where the sister I just had the huge blow up with is also active. 

So I was at our family's annual superbowl/womenbeatingday party which is usually pretty fun because for the most part it's the only day I see all of my brothers and sisters in one place. I have two nieces that adore me but I truly don't get along with my sister so I see them at this party and the random times my mom will have them. 


Since I haven't seen them since just after Halloween, I was asking them what the got for Giftmas? We had a great conversation and they were so cute. My sister had to plow her way into the conversation and told me "in our family, we will call it christmas." I told her in my house, I don't. She said that that while I'm talking with her children she insisted I keep in mind the reason for the holiday. I was totally laughing my ass off because when she left I started telling the girls that actually Giftmas is not really "christian" at all, it's just a redoing of a pagan ceremony of Saturnalia in order to trick people into giving money to the church. I wasn't aware that my sister was eavesdropping and she told me that she didn't appreciate what I was doing and took the girls away. I asked her what I was doing and she said one of the reasons she and I can't get along is because I'm so "fucking dense."; I told her that was nice language to use in front of her kids. She told me that maybe it was better if I left. I told her that it wasn't her house. 


My mom asked me what was wrong, I told her that I refuse to say christmas and that Patty is freaking out because I call the holiday Giftmas. My mom said that it sounded like I was starting trouble, I told my mom about Patty swearing and as per usual she took her side and basically said I should go home. 


Not wanting big drama, I just left and came to a friends house. 


Am I the asshole here? I pretty much feel like I should be allowed to use whatever words I want.
