PED controversy is a f***ing joke. An arbitrary line is drawn, some substances are deemed acceptable and others illicit. The pharmacological differences between the two groups may not justify such a distinction.
The most common complaint seems to be "it's unfair to past generations of players and their respective accomplishments to allow the use of these substances". Should current players be prevented from utilizing modern medicine, equipment, diet and fitness training, keeping variables constant for the sake of comparison? Obviously not, it's just nonsensical to compare players of vastly different eras, PEDs are largely irrelevant.
Nobody would say that modern academics are disgracing the accomplishments of their predecessors because they're hopped up on Redbull and Adderall, why apply that logic to sports which are relatively inconsequential? Progress will continue to be made, to do anything other than embrace it will be bad for athletics as a whole.
