Since you seem unwilling to just discuss technical aspects of things, I
have
to conclude that you simply do not understand what it is you read and
quote.
Too many times you quote out of context.  I don't know where that is
because
you are trying to be manipulative or simply on account of ignorance. 
There
is that old sayind "Do not ascribe to malice that which can be explained
by
ignorance".  I don't know if I should follow it's advice.

There is no point in spending the effort to find some quotable source
because
you wouldn't know what to do with it.  How could you possibly comprehend
what
I would give you if you can't even comprehend what you post.

After this round of followups, I'm done with this thread and I'm done
replying
to you.  If curing your ignorance is in your future, it will have to be
from
someone else.
