Forgive me if I missed it, but I thought you were saying why others might feel that way - which sorta sounds like what matters to you is how others might feel about a lack of 'manliness'???
Edit - just checked back - I still can't see where you say why you think the activity itself is wrong - only where others have thrown it in your face and how you wish to reject it..
Are you so sure? Do you really think few else here have experienced denial - why else is so much said about purging?
