Input: I'll be honest.  I don't think I am an asshole at all for this, but several family members have started to give me shit for this so I figured I'd check in with you guys.

During the winter holiday season my family gets together a lot.  Like we have a mini Christmas party every weekend between Thanksgiving and Xmas, and those holiday get togethers tend to be an overnight kinda thing.  So for about  2 months out of the year I spend the majority of my free time with extended family.  I love this, but as many of you can sympathize (I hope) this also involves a lot of my relatives getting into heated drunken political "debates."

I am incredibly uncomfortable being around my family when they get like this so I recently started leaving the room and finding something to do elsewhere while they fight so I don't end up an anxiety riddled mess watching it unfold in front of me.  It worked great until a few days ago when an argument about immigration started up and I stood up to excuse myself for a bit.  My cousin and uncle sitting next to me asked where I was going and I explained I was gonna head outside for a bit.  Got some weird looks, but that was about it.

Next day I wake up to find a bunch of texts from that uncle, my father, and a different cousin saying it was "rude and disrespectful" to leave for long periods of time during "family time."  I responded that I didn't like sitting around listening to them yell at each other over politics, but they say that is "just what families do" and I should "get over it and stop being a snowflake."

I'm honestly considering either skipping the rest of the holidays with them or only showing up long enough to see my younger cousins and my nephew that I love to pieces.  (He is so goddamn cute it kills me.)  I enjoy the majority of these events, but as soon as the alcohol comes out I feel like the odds of it staying pleasant go down dramatically.

I am 99% sure I am not the asshole on this, but if there is a legit chance I am just missing some social norm here I would love to know.  Is this "just what families do" or am I in the right to remove myself from the situation when it does nothing but make me miserable to be around?

quickly leaving the room whenever my family moves conversation to topics that I know will get uncomfortably heated
