Charlie,
That was an unproven allegation by a less than honorable person with an ax to grind and no ne’emanus. He has been known to spread falsehoods regarding metzizah b’peh in the past. (Besides a number of other falsehoods as well).
But like I saw a poster comment on another site regarding this issue. The weather in SF is nicer than New York. And therefore there is nothing wrong with them trying to outlaw milah.
Your comment about the dangers of mila should really specify that the most complications come from those who use the a clamp when doing mila. It is a known contributor of complications including amputation. Besides for causing significant additional pain to the baby.
There many less complicataions from mohalim doing metzizah b’peh than there are with mohalim using clamps.
