Clear enough? You were operating under misinformation, which I corrected.
You went way beyond "correcting" it. You took such a vicious attitude that it sounded like you were judging me for my innocent attempt to find some chronological information about the universe. I didn't know what parts were introduced by which author; I was just trying to research the question. And you jumped down my throat for daring to consult a reference that didn't meet with your approval. So hell yes, I felt attacked. Anyone would if they got that kind of vitriol in response to an innocent attempt at research.
