Hi Chuck,
Happy 4th of July - I knew my words were bound to light the fuse on
someone's fireworks.

Honestly though, my statement brings up a valid point and I don't see
why my opinion needs data behind it. The proof should fall on the
other side, proving that the chemical is indeed safe.  Until that
proof is there, it is wise (even if inconvenient) to err on the side
of precaution.
