Let's approach this from a more visceral perspective
If the clap was going around most sexually active people would get tested to know if they had it and if they needed treatment and needed to keep It in their respective pants for a couple weeks.
If posada got tested and had the clap, he'd have to stop hooking up (That presumes he actually does, which is a shaky presumption)
So he would he would argue that testing didn't matter and made no sense.
Then the entire community of trolls would be infected and and clinics would be overrun, preventing Drs from giving kids stitches for merry go round falls, resulting in them having scars.
