Posting from an alt, to make a long story short, we got into an argument about politics, happens every so often as she gets involved emotionally a lot (we have the same inherent views but I see it as top vs bottom as she sees it as left vs right). She is trans and is having a rough time at the moment with the election, she recently bought a large dagger and carries it with her everywhere as she thinks she is going to be arrested. I try to support her the best I can, but she ends up bringing politics into almost everything and I have mentioned that being an issue a few times. She has had paranoid moments in the past and has had gangstalking delusions.
We were watching a video about the trans cult murders that happened and she said that the murders may be justified because the people killed were possibly transphobes...?? She then says that all conservatives want her dead so in turn she wants everyone in that party dead as well and hates them all. She supports locking people up for thought crimes as well. I say sweeping generalizations divide us more as a whole. She then says that that is part of the problem and we start arguing more. I tell her there is a difference between holding views and acting on them. After she mentioned the killing of conservatives I grabbed my pocket knife and put it in my pocket as I was uncomfortable and she called me out on it. She tried touching me to calm me but I backed up a little as I froze up a bit as well.
Fast forward to after work later, she texts me asking if I want to come over. I tell her that my mental health isn't the best and if she is going to start bringing up politics I can't do it for the night and that we can resume in the morning. She then starts getting mad and tells me that because I'm her partner I have to be there for her (implying that I don't do it for her every other time) and that the boundary doesnt make sense. I tell her I am going to bed and I do not wish to resume the conversation until we both cool off. She implies that I need more meds because I don't want politics for one day as I am bipolar as if that contributes
In the morning I told her I was tired and stressed so I wasn't up to it, and told her that pushing my boundaries wasn't right. She then says that I am a sympathizer for conservatives (implying they're all nazis) and that I support them. She then tells me it's either hating all conservatives or the relationship. I honestly fear something might happen to me in my sleep or she may snap honestly, the night prior scared me.
I am living in the twilight zone or something dawg bc this shit ain't making sense

she gets pissed and I'm the bad guy because I put up a boundary for one day? I feel like im not the asshole in this. What do I do? I legit am fearful to an extent as she has extreme black and white thinking. I always validate her but the one time I don't I'm awful. Any feedback is welcomed.
