The Static vs. The Staphylococcal Penicillin

The static versus societal thing, I think it's actually pretty well known in the IT community now is absolute nonsense. The fact that there's plenty of antibiotics like Linnaislid is about to be a static antibiotic and has gone head-to-head with flu clocks for treatment of staphyl race infection. So why do we keep teaching it? And anybody who's that static? Why are we perpetuating this?
