This word has become an offensive staple for intact men. It’s no loner used among “uncircumcised”(intact) men because it makes no sense at all.
The prefix “UN” means to go back and “undo” or not do something.
“Circumcised” means that a male had is foreskin removed.
The word “uncircumcised” is just ghastly. You are leaving a body part as-is and as nature intended. You are not going and undoing something. Intact – with foreskin is default. Does this make sense?
