I don't think that's what it is.

The problem is when you speak in absolutes while simultaneously "not meaning it" that way, is that this is not conveyed to the people you are speaking to, so we can only assume that you did mean it, and now we think you're being unreasonably generalizing.

And I think it's pretty hard to have a useful conversation if we cannot use agreed upon terms to convey what we mean. If you know that not everyone will understand your intention by saying it that way, then why do it?
