I don't think that they eat the foreskin, although they do, in some version of the ceremony, suck blood from the baby's penis and spit it into a cup of wine. Some have claimed that the wine is then drunk by the person performing the ritual, but I can't say that this actually happens. I don't even think every Jewish circumcision includes the person putting their mouth on the baby's penis. My neighbors invited my husband to carry their son across the threshold when they had the circumcision done at their house and it did not involve any mouth to penis contact. Perhaps only the very extreme sects of Judaism include this as part of the ritual. Just like only some Christians handle snakes or practice polygamy. Every religion has its crazies. (And even atheists have their crazies, too). I don't think it is fair to judge all members of a religion based upon what some of them do.

They want everyone to hate the Jews.
