Believe me, I understand all those arguments and they are not wrong, but it just "hurts" the way I see anonymity. For me it literaly means "without a name" and you stick a name on the AM.
And remember, the worst of atrocities have been done under the umbrella of "it is best for society". :)
For me "anonymity" is a goal in itself, for you it seems that it is just a cloak which allows one to hold a conversation for which one cannot be held accountable or censured by negative XP and the "branding" allows such conversations to be held clearly. I think that is a perversion of the concept of AM.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
