I think anonymous or not we should write what we want because it’s our voice. We need to understand the consequences if we write something that’s not a good topic and can do things to potentially mitigate the damage or issues related to it. Writing what we want though is important because it goes back to free speech - we need to be able to speak freely to uncover ideas and things that we need to do differently or modify to grow and be better people and societies.
Having to self censor is not a good thing for that in the long run!
