No, you weren’t. You were injecting your own pseudoscienentific opinion. AZT did not “kill thousands” and the article did not make that claim, so you’re sourcing it from a notable liar.

If you want to talk about why the study was not ideally run, be my guest, but AZT is effective for what it does: Preventing HIV from using the cheapest pathway to insert itself into your genome. It is why it’s still part of the drug cocktail to this day.
