The different post

So I recently made a blog about my thoughts about Taylor swift because she has a chokehold on my band mate that I just don't understand. I'm ranting here because this girl is 1. my friend and 2. sensitive apparently. I'm low-key asking for tips on how to go about this becuase I'm someone who loves to fight and argue and that you couldn't not beat but this again is my bandmate. (also the fight was stupid as fuck). so most of our band does NOT like Taylor swift except for this girl. someone made a backhanded comment about Taylor swift and for some reason she blew up and doesn't want to say anything to the actual chat but instead leaving shady Instagram notes about us. I thought this girl was my friend but she seems to be taking it out on me the most even though I probably said the least. I was literally trembling not to blow up on her for being a petty bitch about literally fucking nothing. especially since I'm not one to bite my tongue... what do I do with this? because I've really been trying to keep the peace... but shes making it hard.
