You are speaking of an ancient practice that led to fewer infections for infants, men and the women that they later married.
Back when the practice of filling the mohel’s mouth with wine and covering the freshly circumcised penis with that wine was first done, humanity had no knowledge of bacteria. The mohel was giving the infant an antibiotic covering over the fresh wound. We didn’t know why it worked, but it did. If the mohel performed his duties well, the child wouldn’t become infected.
Anti-semites have perverted the practice. Made it sound like some sort of child molestation.
It’s not. It’s sanitation.
Now, in my mind, there is no reason for anyone but a Jew to do this. If others want to follow the example, fine. But our ways have proven sound for three thousand years and work for US. There are many more traditions that have have proven protection for our health in the long run, in addition to this one.
Why don't you call for the stoning to death of those who disobey the "laws" of your cult as in Deutoronomy, for the sake of intellectual honesty? The Torah is "forever", after all, and doesn't it call for stoning-to-death punishments for several mundane acts? If you can disobey these, then why not the circumcision requirements? Why this selective application of the Torah? Also call for animal sacrifices while at it. Because, otherwise, you are picking and choosing tenets of your religion to your satisfaction...
