Random testing should be an option, not a requirement. This isn't a court order where your parole officer can just show up and drug test you. It's way too expensive to randomly test fighters. Imagine people asking for it in the amateurs, or just small time fights, etc. No one wants to pay for that. So what defines it? PPV main event fighters? I think it should be agreed upon by both camps, and the cost split by both camps. If not, then you can't enforce random drug testing.
Also, no one ever called you racist.
Biased, yes...
