"Myth" would be a perfectly appropriate answer to all of the above.
I know there are links that explode all these myths, let me see if I can post a couple:
Dispelling the cancer mythCirc doesn't prevent STDs Circ doesn't prevent HIV transmission
Think about this one logically....US has highest rate of circed men in developed world.....US has highest rate of HIV infection in developed world. Hmmm...

In fact, the foreskin has important immunological functions and helps prevent disease transmission.
I don't know what "infections" she's talking about but let's not forget to
dispel the UTI myth as well as the
myth that smegma (which means soap in Greek) is dirty.
Adhesions (what she means by strictures, perhaps?) are generally caused by rips in the foreskin that occur when ill-advised parents and/or doctors try to retract a baby's or child's foreskin. The foreskin is attached to the glans at birth the same way the fingernails are attached to the finger. If the foreskin is pushed back (totally unnecessarily) then you get rips and tears that may heal into adhesions. If the penis is left alone as it should be, and the only person to retract the foreskin is the owner of the penis himself, then voila no problems with adhesions.
Lichen schlerosis (aka BXO) is rare and affects only 6 in 1000, and there are treatments other than circ. See
http://www.cirp.org/library/treatment/BXO/
In short, there are no compelling medical reasons for universal circ. There is no medical society in the world that recommends routine infant circ for medical reasons.
But MOST IMPORTANT, ask these people what they know about the benefits and functions of the foreskin. It is vital to normal sexual functioning and normal male sexual pleasure. Why cut off a normal part of the human body for no good reason?

And this doesn't even get into the human rights issues involved in cutting off the most sensitive part of someone else's body without their permission - especially when it's inflicted (mostly without anesthesia) on a defenseless newborn baby. The more you learn, the more horrible circumcision turns out to be.
HTH!
