So god supposedly said, "I want you to prove your love for and devotion to me by cutting off the end of your dick. And just to be sure you're serious, cut off the end of your kids' dicks too!"
That's some seriously fucked up shit.
Religions are highly articulated expressions of mental illness.
Jews don't believe circumcision was a directive that came straight from God like Jehovah's Witnesses do or as you proposed in your comments.
Again, as I've already stated above, the Hebrew Bible is not meant to be a historically factual work. It is a liturgical collection.
Liturgy is something Jehovah's Witnesses don't have in their religion like most others do, so this leaves their adherents and even their ex-members somewhat ignorant and without a reference of what a liturgical works is.
Meant for public proclamation during formal worship to give religious explanation for cultural celebrations and customs, liturgy consists mostly of religious folklore. It gives a religious "explanation" for why a community does something.
But you're in good company if you think it's "fucked up shit." Let's see, there's the Spanish Inquisition judges and clergy, the murderous mobs of pogroms that would constantly attack us, the Nazis who murdered us in concentration camps--they all felt the same way about our practice and views on circumcision. So get in line.
There's been a whole lot of others here before you. They never lasted, they went down in infamy, and probably like you, they thought it would never happen to them because they felt they were in the right...probably like you do now.
