@goatsarah Um… I disagree with your paraphrasing of the answer you gave though. To my eyes at least, you went: "This is the history. This is why it makes sense."
And their response was along the lines of: "Thanks for the history. I meant it when I asked people not to explain why they think it makes sense today though."
Given the sheer volume of responses the OP gets from Reply Guys when they ask questions like that, I can understand why they might reply to you that way. Maybe you overreacted?
