First of all I have never heard the term "objectifying" and since when does striving to be the best in any sport hurt that sport?
Does Tiger Woods hurt golf? Did Carl Lewis hurt track? Did the Celtics or the Lakers hurt the NBA? Did the Yankees or the St Louis Cardinals hurt baseball? Did the Dallas Cowboys or the Green Bay Packers hurt the NFL? Did Muhammad Ali hurt Boxing? Does Roger Federer hurt Tennis? Does Duke or did UCLA hurt College Basketball? Did the Montreal Canadiens hurt Hockey? Did Secretariat hurt Horse racing? Did Richard Petty or Dale Earnhardt hurt NASCAR?
What the heck are you talking about?
