Was that written by an LLM? It isn't that it's a mere opinion, it's that when every word out there has to be scrutinized for the possibility that an AI output it instead of a human intelligence that it gets pathological. Am I an LLM with the right prompts set up to respond this way? I mean, I know I'm not, but everyone else out there is just going to have to trust me that I'm not.

I wasn't suggesting you have a mental illness for having an opinion.

More, commenting that just as bad as generated content if not worse is every thread where the top comment is an accusation and ensuing witch hunt.

So, no, having an opinion is not a mental illness. Feeling compelled to call it out and discuss it on everything one reads may just be.
