If "chad" is hooking up with four disease-ridden sluts, and non-diseased women avoid "chad," then chad's foursome is probably just the sharing of microbes between the already-diseased. If "Chad" is seeking out the non-infected and infecting them with STIs, then "Chad" is harming public health. Either way, this is not a personal problem, this is a social issue. Also, it will not be solved by snarky one-liners, it will be solved by serious analyses, solid definitions, and practical actions.
