Because you don't believe in it, does not mean it's wrong, or traumatic.
And for the record, I did not state circumcision was wrong. I in fact stated nothing about whether or not I agree or disagree with people circumcising for cultural reasons, and thus you have absolutely no way of knowing whether or not I think it's ethical.
I said I am against it because of the fact that it is a traumatic experience for the infant. That has nothing to do with whether or not it is objectively culturally wrong. I don't have the right to suggest that someone's religious beliefs are incorrect. Thus, I don't bring personal religious beliefs into it at all.
I stated it was medically pointless and causes physiological damage - as well as causing enough pain to adequately be classified as traumatic to the infant experiencing it. I also stated it was genital mutilation. None of those statements approach whether or not I feel it is wrong. They are simply factual statements. I call it what it is, which has nothing to do with ethical judgment.
