PBA, point one is semantics If you are opposed to THIS law only because of where it will lead then you are not opposed to THIS law.
Point 3 (as you explain it now) is part of point 2 since you agree (i assume) If it WAS dangerous then you would support regulating a religous ritual.
As to point #2, the studies are not relevant to me. Most Doctors view MBP as putting infants at risk. Anecdotaly the evidence against MBP is overwhelming speak to pediatricians even frum ones (I have) speak to residents both here and in Israel (I have) the number of frum boys who come in with infections (not just HSV) far outweighs the number of frum girls and the number of boys in general. Admittedly this is anectdotal and no reason to ban or limit Mbp.
The only thing I support is getting parents permission and informing them of possible risk.
Do you mind answering a question? Do you think a hired mohel should specifically ask parents if theyd like MBP done? (They dont ask about technical aspects of the bris, even halachic ones. For example the mohel wouldnt ask if he should do priah as part of the chituch or separately with his nail) Or should the mohel be allowed to decide on his own wether to do it or not?
