I think it's less about content topic and more meta content topic. EG I don't want to remove pictures of broccoli because I don't like broccoli, I'm trying to remove pictures of food because it makes me eat more. Similarly, I don't want to remove Political Takes I Disagree With, I want to remove Political Takes Designed To Make Me Angry. The latter has a destructive viral effect whose antidote is inattention.

Echo chamber is a loaded term. Nobody is upset about the Not Murdering People Randomly echo chamber we've created for ourselves in civilised society, and with good reason. Many ideologies are internally stable and don't virally cause the breakdown of society. The concerning echo chambers are the ones that intensify and self-reinforce when left alone.
