gordiano - are you saying bodybuilding has no mainstream appeal? 
What's wrong wth you, bro!?? By all means pro. BB has "mainstream appeal"!!
It appeals to those mainstream weirdos involved in such estimable pursuits as illegal drug-use, illegal drug-dealing, being freak show contestants along with their salivating homosexual and submissive schmoe fans!!!
Long live pro. BB...the all-American, wholesome, sport...with such wonderful role models as "Mr. Intelligent Articulate", Ronnie Coleman; and "Mr./Ms. Law-Abiding Citizens", like Craig Titus, Bertil Fox and Sally McNeil; for all the impressionable youth of America to look up to!!!
