To start with, I don't have any issues with circumcision being done to informed individuals who want the procedure. What I do have an issue with is the procedure being done to infants or minors who don't understand the benefits and drawbacks of it, and can't consent to it.
Now, it's worth noting that the scientific benefits and drawbacks of circumcision are not fully clear. There is a fair amount of disagreement on just what results it produces. If it was the case that circumcision was 100% (or closely enough) proven to be healthy and non harmful to infants, then I could support it being done to infants.
However, this is not the case. Here are a few studies showing that it isn't fully proven to not be harmful.

Considering this, I don't think that it's right to allow the procedure to be done on infants when it isn't fully proven to be beneficial and non harmful. I also think that this sort of medical reasoning should trump religious reasons for circumcision in all cases.
What are your thoughts?
