The Vatican's recent statement on condoms certainly isn't the first time this flawed logic has been used. I have heard other people say that you shouldn't teach kids about birth control, or you shouldn't call it safe sex, simply because no method is 100% effective. This logic even spun "Statistics show no correlation between teaching women how to do breast self-exams and [it was either surviving breast cancer or finding malignant tumours]" into "Breast self-exams are BAD!" But it's still a huge-ass logical fallacy, as can be proven by applying it to other areas of life.

Have you ever had your computer crash? You shouldn't use computers! They don't work!

Has your car ever stalled? Don't use cars, they're unreliable!

Remember that blackout a couple of months ago? We should stop using electricity!

Has you ever had to plunger your toilet? See, indoor plumbing doesn't work! Do away with it!

Has a vending machine ever refused your quarters? Has a debit machine ever refused to swipe your card? Better do away with the exchange of money for goods and services!

Have you ever eaten something that doesn't agree with you? Better stop eating!
