Over the years, thanks to my interest in men's issues, I kept seeing various objections to routine and ritual male genital mutilation from various authors. However, it didn't stick with me for several reasons --
1, none of these sources ever really got down into the details about why it was so wrong and harmful;
2, I was more interested in other men's issues that were more immediately and personally obvious to me (domestic violence and false accusation in particular, having been through both myself), and;
3, I shared, without realizing it, much of the general culturally programmed attitude of just reactively trivializing and then ignoring the problem.
However, in mid-1995 my intact father suffered a massive stroke and I came home from NYC to take care of him. While he was recovering from that and from the cranial surgeries done to relieve the hematoma, a couple of the doctors on his team suggested that we have him prepucectomized. But when I started asking them why and how it would benefit him, they stopped giving me straight answers.
So, I put a hold on that decision, and when I had some free time, I went to the library and started doing some research. There wasn't much in print, but they did have a copy of Rosemary Romberg's intactivist book from many years ago, and that was enough to show me that there were indeed two very different sides to the subject. So then I went online through library access and started finding out all sorts of things that the mainstream information sources were not presenting. That was enough for me to go back to his doctors and say, "Definitely not!"
A couple of years later I got internet access at home and began spending a lot of time on abUsenet, being a rage junkie and venting my bile against bigoted femelitist vermin who were also looking for a fight. Since the forums I was most involved in were about gender issues, the topic of routine and ritual male genital mutilation kept coming up, so I went looking for more information and citations in order to be able to argue authoritatively on the subject. Eventually, somewhere along the line, I finally internalized everything I was learning and realized at a deep identity self-definition level that I had been victimized in this fashion. That, combined with my realization of just how few people were actually actively working to stop this, and just how massive the task was, was enough for me to decide to make intactivism a priority in my life.
