Definition: Given a real-life anecdote of a complex ethical situation, generate a suitable title that describes the main event/root cause of the situation. Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: I'll try to make this as quick as I can, and this is an alt account because my friend has my main. In short, I have a friend named B who started becoming very... sensitive the last few years. Of course, I'm not judgmental about how people express themselves, but B is very, how do I put this... Tumblr-y, if you catch my drift. We share a lot of the same opinions, so I'm not criticizing their beliefs, but I mean they're very sensitive and use words they saw a post about, and this often ends with them calling any relationship where they and their partner break up as "abusive" and "toxic".

I'm an abuse victim in several different ways, so the first time this happened I was horrified and asked B about it all, and they essentially just came back with "Well they were passive aggressive a lot" which I totally get is toxic behavior, but so far ever past relationship they've been in is now deemed "abusive". Even relationships where B was fine at first with them breaking up are now deemed abusive. Now, B has a good idea of what abuse is as their parents were pretty emotionally distant and their dad was downright emotionally manipulative, but the things B has deemed abuse in their romantic relationships is completely ridiculous. 

On top of this, over the past few years they've also gained more and more mental illnesses, and now I think they say they have DID, BPD, PTSD, Bipolar disorder, depression, anxiety, the list goes on. I try to leave this topic where it is because I'm not going to try and analyze someone's personal life like this, but people with BPD typically have issues with relationships and B refuses to accept that their partners aren't abusive for being a furry (literally an argument) and that the unsteady nature of their relationships could be because of their BPD.

While that's all frustrating, they also use the words trauma very liberally, and say they understand it very well but have some faulty ideals about it. I can remember one time I was talking about a character from a game we both played that was traumatized and angry, and I said I liked him because I could relate to the feeling. B started talking about how awful he was, how he was mean and a bad person, and I replied that he was obviously traumatized. B got defensive and said they KNEW how trauma worked, and they knew that's why of course, but they still thought he was bad. Weird thing to be offended by on my part, of course, but this was just the most recent example. B labels a lot of things trauma (one of their exes, The Furry, made them a fursona, so now any mention of fursonas is traumatic for B) yet often fails to recognize trauma in anyone else except really personal and common things for them.

Am I the asshole for being angry about this?
