There's been alot of buzz lately around the news that circumcision reduces the chance to get the HPV virus - warts (in this case, genital warts). This is not news, people. The basic idea here is that if you cut off a body part it won't get sick.
We don't need scientists wasting money with studies to find these things out. So now it's even quantified how much. Guess what? There's already a vaccine for that. Condoms work, too.
So now you can see what I mean in the post title, "Bad Medicine". First of all, cutting off body parts that aren't sick yet is immoral, unethical ("first, do no harm"). But beyond that, the vaccine and condoms should suffice for HPV. No dongle truncating required.
