Would you call it an ugh field, or something less significant?

Both less significant in the sense that it isn't a strong feeling and in that ugh fields represent a different kind of thing. They inhibit thinking about a topic rather than just being representations of a preference. In this case the feeling represents the thought "Why is someone starting a topic without having something to say about it? That's pointless."
