Interesting question. In relation to music and art, I don't think there's a single person on the planet who is truly objective. We might all be equal but we're not all the same.
We form opinions and bias from a very early age. Subjectivity sometimes arises from objectivity. Sometimes it just happens by itself.
I love a pretty tune as much as the next person. But there's a lot of music around that isn't beautiful - people listen to it because it's challenging and interesting. And then we get back to objectivity.
Everything is objective. If not, then why would anyone bother doing something. It's just that some things are more fake because of what was intended.
Its like pop vs rock and abstract vs cliché.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
