you're not responding to a 10 year old.  you are responding to an adult who has taken your insanely stupid comment and proven it wrong.  you have not only discredited any future posts or threads you comment on, you have proven your level of maturity by resorting to blanket insults.  you, my friend, are the brat who refuses to admit fault, error, or an innacurate claim.
"shut the fuck up"....hmmm, now that is how a pre-teen responds to someone backing them in a corner.  i think the more appropriate response would have been, "you know what, geesh... i said some dumb stuff and now that i look like such a moron on here i should just go ahead and admit that i had no idea what i was talking about.  when i woke up this morning i logged into NS and decided to jump into a conversation that i knew nothing about.  man, that was a bad idea because i don't know anything about big mountain.  i though making some sort of absurd claim would be a good idea but looking back now, i wish i really hadn't."
