The primary objection to this consent form is that it is not merely just a consent form, but rather it contains specific objectionable language attempting to frighten parents away from doing MBP with language that falsely claims MBP is dangerous and causes brain damage and death.
Aside from the above required language on the form being false, it illegally forces the mohel to share the government’s opinion on the issue that he doesn’t agree with. That is a violation of the free speech provision in the Constitution.
(As an aside, there are absolutely no legal restrictions on clergy in NY performing a religious marriage ceremony without the couple obtaining a civil marriage.)
