Why do people idolize Bonds, Muhmmad.Ali, Armstrong etc..?

They are all steriod users excluding Ali. There's no way in hell Armstrong can win was it 7 tour De France's? He was on steriods and he knows it and we all know it. He plays that sympathy role of beating cancer, so everybody can feel sorry and happy for him. He's a steriod user as well as Bonds, Sosa, McGwire. For Muhmmad Ali, he was a prick, lol. Ohhh....so he doges the Vitnam War and now he is celebrayed? This guy said "I am the greatest" and that going against the face of God, no wonder he has Parkinsons or something diease.
