no, not circumcision in general, but circumcision on children who have no choice in the matter. consenting adults can chop off whatever parts of their body that theyd like.
circumcision has a few minor benefits, like reduced chance of certain infections and cancers (duh, if a part is gone, it cant get infected!)
but is it worth it? it permanently removes a part of the body that does affect sexual function, it is extremely painful (especially if done after infancy), and as with any operation, there is a chance of complications.
no medical association in america supports forced circumcision, and many are against it, including several pediatric associations.
i find forced circumcision to be a cruel and barbaric practice that should be made illegal. the decision to perform bodily modifications on somebody should belong to that person and *only* that person.
