You called me stupid, and when given an opportunity to retract the
label, you instead reaffirmed it. You based your assessment on the fact
that I see the risk of using PVC for compressed air as so miniscule as
to be negligible, while you see the risk as unacceptably large.

Each of our opinions are valid. To hold another as stupid because he
doesn't share your opinion, is pretty much the definition of closed
minded.

You do have a point. You are not stupid, you just did one stupid thing.

Life is not without risk, but when you knowingly take the risk rather than
the readily available alternatives, well . . . . . . our opinions differ.
