Opening a thread to discuss this. For those unaware it is the suction of blood from a newborns circumcised penis by the mouth of a mohel.
Mishnah Shabbat 19:2 --- "One may do whatever is necessary for a circumcision on Shabbat. One may circumcise, and tear [the membrane], and suck [the blood], and put a bandage and cumin on it. If he did not grind it [the cumin] on Shabbat eve he may chew it with his teeth and put it on."
Child genital mutilation is a horrible practice and should not have religious protections. How can anyone defend the act of oral suction on an infant? I would love for you to chime in with your two shekels @Joe_McCarthy.
