That blind people know what sight is and how it would effect their lives, but so far nobody has been able to tell me how the experience of having a foreskin would make my life better in any way.
It's not the be-all and end-all of whether it is OK to do it or not, despite your endlessly repeated mantra of "well it never did me any harm". I do think you are conditioned to believe that it is though.
This coming from someone who straight-facedly talks about 'harm' without any negative consequences.
I have already explained in detail, with a dictionary definition, why cutting off a healthy part of a body without consent constitutes doing
the body cosmetic harm. Now why don't you take the same definition and explain why it doesn't? Why does the fact that there may be no further consequences mean that cutting off a body part isn't harming a body?
