Against unless it's necessary due to medical condition (like Phimosis). I have an ex-Muslim friend who wished his parent's wouldn't have done that to him, since he's afraid it has affected sensitivity and that he feels less compared to uncircumcised dudes. Also it makes me laugh how some pro-circumcision people are like 'but it's unhygienic to keep it' as if washing your genitalia was an alien concept to them.
