How you are brought up has nothing to do with cold hard facts.
It isn't a fact though. You believe that it's a fact because:
(a)you are thick- headed
(b)it's what you've been told is the truth
(c)it's what you want to believe
(d)you've rationalised the subject (as i have) however you came to a different conclusion to me, which is fine.
i don't understand why you're all so upset simply because i have a different opinion to you...
