This sounds a lot more like NTPs than NTJs. NTJs are usually annoyed with people that they see as spending too much time focusing on arbitrary definitional precision (this is one thing they tend to dislike about NTPs.)
Anyway, the people you're arguing with in these cases probably are not intentionally steering the conversation into semantics just for the sake of frustrating you. NTPs tend to insist on this sort of precision (many would describe it as nitpicking) because we're very keenly aware of subtle differences in shades of meaning. When you use one word but we can tell from context that you meant something that that word doesn't actually mean, we want to correct you because we feel that misinterpretation of each other's ideas is inevitable if you don't know the right words to properly convey the ideas you're trying to express.
The miscommunication usually happens when someone uses the wrong word or wrong shade of meaning, and when you do this NTPs will often focus on correcting your terminology even though we're able to intuit what it is that you actually meant to say. Ironically, you see this as us "ignoring what's actually being said", but in reality we're often more aware of what you actually said than you are. We realize that you said something that doesn't align with what you actually intended to say and we want to clear up this misunderstanding so we can communicate more effectively with you.
What you want us to do is to focus on what you meant, but we find it difficult to discuss anything meaningfully until the terminology is defined clearly and precisely, which doesn't happen if there's a disconnect between your idea of the terminology and ours.
We're generally not doing this just to annoy you, but rather because we insist on having a common language defined before any meaningful discussion can occur.
From your perspective, you may not understand the difference between the terms you're using and the terms we're asking you to use instead, so it looks like we're ignoring your point and focusing on errors in your wording instead. Admittedly, we do this sometimes when we could just intuit what you meant based on context and adjust our responses to it, but again, we don't like having formal discussions until we're both on the same page about the terms we're using and their precise shades of meaning.
