Why are players tested and punished for use of recreational drugs?
Techinically they're not cheating, its their personal lives! Because what you do outside of a tennis court can bring the sport into disrepute! People don't just say Maragret Court is a homphobe or a racist ...etc they say Maragret Court the Australian tennis player is a homphobe or a racist
That argument is flawed because drug testing is in direct link to the possible validity of one's athletic achievement in which the sport wants to be drug-free. And which players agree to adhere to, knowing that basically drug testing means they are presumed guilty if or until the test proves the counter.
People can agree to disagree and proceed as they see acceptable.
And changing hearts and minds take time which is a foreign concept in an instant modern society. And I will say that returning venom with venom will make any fight that much harder.
In regards to BJK, Navratilova, & Stubbs, it was good and wise to refute the comments without nastiness whether warranted or not.
