Well, that's actually just straight-up false. Character and emotion are important but have never precluded having something to say about the wider world, or engaging with big ideas. SF in general and Trek in particular are full of stories that manage both. (NuTrek not so much, wulfio is right about that, but that has nothing to do with the general rules of writing or creating. It's a specific choice.) While I get that you're irritated by the fallacy of being asked to choose from a Menu of Cerebral Things, basically what BillJ is trying to tell you is that disagree with him or not, Greg is a good and smart guy and you're getting needlessly personal about it.
