It's fine to disagree about books, music etc, and even to have heated arguments about a particular band/author/film director. It's a problem when one person is continually bashing everything the other person likes, because that's not about the music or the movie, it's about bullying.
Also a problem and bullying if one person considers themselves the ultimate arbiter of whether anything is of value and gears every conversation about anything to one that is designed to demonstrate their superiority.
This is a level further than bullying as the intention is nothing to do with hurting or upsetting others, it’s incredibly self centred, all about how they are superior. Showing it, revelling in it. Other people’s upset or lack of engagement is only seen in relation to it being an exercise in superiority.
Ex was like this. It was not possible for people to simply like or not like things. There had to be ‘the right way’ to think about things (how he thought and this was ‘the objective standard’) and everything else was ‘the wrong way’.
If pushed re why he felt qualified to be the ultimate arbiter he would descend into ridiculousness such as ‘I played the trumpet as a child’ to justify why he was the ultimate arbiter of the objective standards re ‘the quality’ of music.
If I did not want to enter into these types of conversations and tried to steer them back to ‘well what people like often doesn’t have much to do with what is ‘good’’ I was ‘sitting on the fence’ and this meant I ‘do not have the confidence/knowledge/validity’ to add anything meaningful to the conversation.
If I bit back it would descend deeper and deeper into ridiculousness and would become an exercise in tearing me down personally.
If I said it was hurting my feelings he would say ‘I always forget how sensitive you are’ or ‘I feel like I am always stepping on landmines!’ Or he would point blank stonewall me or make a dramatic fuss of being sad and demand comfort.
If I walked away I would be ‘having a dramatic tantrum’ or ‘being manipulative so you can get the last word’
It was exhausting.
