I never made a claim one way or the other of whether it's safe or not. I just stated a fact.
For all we know copper will prove to be like asbestos. Personally, I doubt that very much. Just as I doubt PEX to be less healthy than copper. I do believe that R&D has advanced far enough that Im confident that it's safe.
Personally this doesn't look too appealing to have my drinking water flow through either: (BTW. ..ever seen the insides of the 30 miles of supply line to your houses?)
