If I had an open wound on my body, I would imagine rubbing excrement in it would cause infection. For hemorrhoids, it is often the excrement that causes the bleeding as it rubs itself on the wound. How are hemorrhoids so common but infection from them not?

The rectum/poop chute also has special powers to fight infection. Considering a bad hemorrhoid is open wound that poop gets rubbed over, realize that the mouth and anus are magical places with superhero capability to fight infection. They have an amazingly good blood supply (a good blood supply means that white blood cell soldiers can be efficiently delivered to the battlefront in cases of early infection), and an ability to heal very very very quickly (think about the last time you bit your cheek. By the following day it was healed). Finally the mouth and the anus have a special type of antibiotic in it that has a “glycoprotein” structure that has very special infection fighting capabilities, pretty much only found in those “high bacteria areas”.
You are right. If you had a similar problem in another poopy area like the right colon (found way up inside your belly cavity) that had the same rough open inflamed structure as a hemorrhoid you might die in a few days.
