I think the problem with the live circ video is that a) there is relatively effective anesthesia, and b) babies heal from circs and go on to be (apparently) happy and healthy with no real effect. Unless her first ds had trouble with his circ, she may just think of the pain as something he has to get through to get to the desired outcome - "it's all over in 15 minutes and then they heal in a week or 2, blah blah blah."
And not everyone has compassion and empathy for a little baby, even one obviously in agony - babies scream like hell during and after vaxes, too, and look how many parents and doctors act as if that's just the price to be paid for a larger benefit, they get over it, blah blah blah.
To my mind, the most compelling information is not about what happens during the circ itself (i.e. the agony) but about what the baby then loses for a lifetime, as well as all the potential complications.
I like the Fleiss reprints you can get from Mothering - it's short but everything is in there. If you send too much you risk that none of it gets read.
Just my .02.
