There are way too many assumptions in your post. Yes, you're right that I like GraphQL, but:
1) Nowhere in my comments did I say that's limited to negative comments. I think "GraphQL is good" is just as useful (meaning not at all).
2) "Criminals are bad" is not an invalid statement, and neither is "GraphQL is bad" or "GraphQL" is good. But if the purpose is to discuss criminality, and not just add noise to an ongoing discussion, it is also a useless statement. Imagine there's a debate panel going on, someone in the crowd stands up and says "criminals are bad!". Where does that lead the conversation?
3) "The plane is about to crash, please pull up" is an expression of fact, not an opinion, and not even something that warrants or is said in a discussion so I don't think the comparison makes sense. Either way, "GraphQL is bad" is an opinion, not a fact, and thus needs more context to be useful in a discussion.
I'm not going to acknowledge the last paragraph because I'm presuming good faith from you, and I'd rather not turn this discussion into speculation about other comments in this thread or why you're here.
That said, you're definitely right that I'm biased towards GraphQL, but I think we're having different discussions if you think we're discussing GraphQL's merits.
