The length of an explanation has no connection to the complexity, validity or soundness of any point, concept or idea under discussion, anywhere, at any time, in any language, so if we're looking for irrelevancies we should start with your complaint.

I would suggest that if you don't wish for your utterances to be examined or misconstrued then you might try to avoid speech that appears threatening, and instead inject more sincerity in any defence you make, otherwise your opponent will feel justified in their scepticism of your intentions.

In short (since you appear to favour succinctness), you'd be wise to be more careful in future ;-)
