for goodness sakes, i object to the original poster saying "it is the
most corrosive/erossive stuff on the planet." and I question the
"universal solvent" cliche , and now I get a cut and paste lecture?
since when has critical thinking been thought of as being
"narcissistic personality disordered "?

guess its better to argue about tires

Why use ignorance when there is so much simple scientific fact
available?
Uhhhh, does it say "solvent" somewhere in this factual statement?

Bob ... welcome to Fryedaye. Was there a thread recently about how
much of a
"cooperative, caring family" this list is? Get over yourselves. Most
LARGE
family's
have individuals with narcissistic personality disordered volks in them.
