the aesthetic side of things is just a by-product of the actual procedure, I'm sure no-one would have it done for those reasons.
For many people, it is a cultural decision and part of their tradition and heritage. If performed properly it does not adversely affect the child. And it can actually increase sensitivity as the glans (head) of the penis is the most sensitive part and without the foreskin can be just as sensitive if not more than it was before.
Those of us with partners who are circumcised will tell you that it certainly does not affect intimacy in any way compared to a non-circumcised man.
It is not right to judge someone who is thinking or has decided to have it done to their son. I think it is important to present a balanced arguement. You may not agree with it, but certainly shouldn't scare monger people into feeling guilty about considering it. If you don't understand the reasons then that's fine, but don't flame the poor woman.
There are plenty of positive examples and stories to back up all your negative ones, as there are with any medical procedure. I'm sure any Doctor will tell you the same thing.
It is Midna and her partners decision and providing they gather all the relevant information and are properly informed on all aspects of the procedure then they should do what they think best.
I've never met a circumcised man, who had it done as a small baby, who resents his parents for the procedure. Most of DHs friends have had it done as part of their culture and they have no adverse feelings whatsoever.
