“Comparing an event in which a woman is cruelly killed to a joyous welcoming celebration of love and a new life is just that: obscene.”
Suttee was a solemn celebration of the wife’s love and commitment to her husband. But that did not change the essential nature of the act. It was, as you say, an event in which a woman is cruelly killed.
A circumcision party may be, as you say, “ a joyous welcoming celebration of love and a new life”, but that does not change the essential nature of the act. A bit of the child is cruelly sliced off.
In both cases, the essential nature of the act is cruel.
In both cases, the religious practitioners regard it as a good thing.
So the comparison holds. The difference between them is the degree of cruelty. Yes, I agree that suttee is a lot more cruel than circumcision, but, since neither cruelty is necessary, I think they should both be forbidden.
“The baby cries and calms down amazingly fast. The place heals within a few days. The procedure and ceremony is performed on 8 day old infants, who retain no memory of the event, hence no trauma.”
But the damage is permanent. The harm has been done.
“I note that you would support a ban. So you may agree to freedom of religion, just not the Jewish religion.”
I would place limits on the freedom of religious practice for the Jewish religion, but also for Islam and all other religions. My principles do not single out Judaism.
But your principles also place limits on the freedom of religious practice. You say “Religious practice cannot be used as a pretext to harm others. You can’t go around killing people and claim that your religion compels you to do so. “
Which means that you would limit the freedom of Hindus to carry out suttee, and the freedom of Aztec priests to offer human hearts to the Sun.
But you want to make an exception for the Jewish religion.
(Incidentally, have you ever been to a Christening? Christians, too, joyously welcome the new life, but many of them do not express their love by cutting off a bit of the child. They just drop a bit of water on it.)
