For me the problem is that virtually all political content and discussion online is very low information. Generally no one is conveying anything I haven't already heard many times, it's mostly remixing slogans and truisms and finding different ways of expressing the same simplified opinion. Questioning that stuff or asking for nuance to be addressed gets met with aggression. The more I'm exposed to it the more I feel like my brain is rotting, definitely does not feel like I'm learning things.
