Bec, i dont think its blackmailing but a true reflection of what they will do if it becomes illegal.
I do really understand where both sides come from, being married to a Jewish man. For my in law family, they were more concerned about hygiene then religious reason.
Although the concern about human right, body choice is very valid, going straight to bash religion/culture beliefs and calling these parents child abusers will not help any baby, it more just shows disrespect, ignorance, arrogance and insentivity. Religion/culture beliefs last for centuries, to change them you need a proper and respectful approach and education over a long period of time.
