I wonder if my slop radar is oversensitive to em dashes and the construction: “it’s not just about foo, it’s about bar” because this post seems human written but the indicators are flashing

There are also many non sequiturs. The sentences only read fine if you don't think about what the author might be trying to say. I also think that this reads like the "author" was an LLM and, therefore, isn't trying to say anything.

À propos of nothing – I'm human and I like using special characters, including en dashes. ;)
