Athletes are generally an awful example to our youth.
The issue I have with this is the hypocrisy. Athletes are not normal humans. Hell, I sometimes think they're barely human. More like X-Men mutants or something. They're not like you and me at all. They're genetically bigger, taller, stronger, faster. They don't eat like you and me, they don't live like you and me, their bodies aren't used the way yours and mine are. They're just about bred for this like race horses.
Nothing about them is normal, yet we pretend that there's some obvious moral line that shouldn't be crossed. Like it's okay to take dietary supplements and have a diet that is completely unlike the diet of an average human(and contrary to any diet recommended by health experts), but it's not okay to take certain other things. As if somehow looking like this is normal and okay if you're not using steroids, but it's wrong and terrible if you are.

The ideal of the amateur athlete made sense. Let's see, among the average members of our society, who is fastest, strongest, or able to throw things most accurately. Just like a 120 years ago, college football meant seeing who can put together the best team of the students that just happen to be attending those colleges. Professional sports changed all this long ago. Everything these guys do is performance-enhancing. It's stupid that all these rules do nothing to actually fix the problem of athletes trying to win by any means necessary. They just throw a few sticks in their spokes and force them to be more creative. If having more red blood cells makes you perform better, all you have to do is figure out a currently legal way to raise that level. Or, you have to find "mutants" who naturally have higher levels. That's cool, apparently, but giving yourself a transfusion of your own blood is not.
It's just hypocrisy. We want to see humans perform at the level far beyond the abilities of an average human, but then we figure that certain ways of accomplishing that should be legal while others should be illegal.
