Was that answer not satisfactory?
In a way, yes. But CE
's non-answer is the issue, here.
Seems to me he answered your question quite nicely.
That's because, like him, you misunderstand the question. Do you have children ? If a child asks her father "why is the Sky blue, daddy ?" do you think "because it's not red" is a valid answer ? Pointing out to the child that there are many different colours is not only trivial but insulting, because that's actually the reason why the kid is asking: she wants to know the cause, not the effect.
I'm very much aware that people have opinions. I happen to have those myself, odd as that may seem. But discussion is, in part, a way to either understand or resolve differences, so basically telling me I shouldn't ask people about their opinions in order for me to understand them better on the reasoning that "that's just the way it is" seems counter-productive. You'd have only threads of people stating their opinions and never discussing anything.
