The only reason people are voting Umich because he is the most neutral stan. He never insults or shades other artist which is of course is good thing for some adversary stanbase since they can trashtalk about Katy without getting trashtalked in return.
umich is a humble member who never posts flamebait threads or discusses trolling methods with other members - something incredibly petty! He does not allow delusion or stan allegiance to blind him, which is why he remains the best Katy Perry stan. (Also he's a poc, so...)
