A good way to prevent misunderstandings like this is to make your points clearer. You rarely post in more than one or two cryptic sentences. Your posting style demands that people read context and meaning into it, so I think it's unfair to get upset just because someone failed to read your mind accurately.
Maybe, but as the moderators point out often, when in doubt, give the benefit of the doubt. And that responsibility is on the reader, not the writer.
