It would heavily depend on the context, I think. The biggest question that would need to be answered is, is the other person engaging in good faith? Or is he trying to troll?
If he’s trolling, he may be trying to do a Gish Gallop, where he constantly brings up vague and untrue points in the hopes that you eventually burn yourself out trying to figure out what he’s talking about.
If he’s not trying to troll, then maybe he thinks you’re trying to sea lion, where someone constantly asks questions in the hopes of burning someone else out.
Otherwise, if it’s in an educational context, he’s expecting that you can figure it out and that doing so will help your comprehension of the material. It’s probably not this.
Based on what you write, I would lean toward that the other person is not engaging in good faith. That being said, without seeing the full context, I cannot fully say that it’s not that you’re the engaging in bad faith (people do tend to romanticize their one side, after all)
