Heh. If it's that hard to say for someone to give a reason, I'm thinking the odds are I'd be wasting my time.
Everybody has opinions. Few manage to distinguish between the opinions they hold and the reasons they hold them.
YMMV.
What you are missing, among many, many points, is that nobody gives a damn if you understand it or not, and nobody is interested in taking the time to explain it to you or locate posts for you because you have no purpose in posting on this subject except to harrass other posters, and that, my friend, is a highly logical inference that any sentient person reading your posts on this subject has drawn.
