Ronald Bailey at Reason magazine points out the strange logic behind some religous figures (who happen to hold some influence over the FDA and this adminstration) disapproval of drugs administered as a result of sexual activity. The rationale is basically this: if you cure people who get sick as a result of sexual activity you take away the motivation not to have sex, so to keep them from having sex we shouldn't give them a cure for, say, HPV or allow them to take the morning after pill.
But, as Bailey explains, this line of logic need not stop at drugs relating to sexual activity. Why not apply this logic to all morally questionable activity? No treatment for obesity, drug abuse, etc.
Oh, what a wonderful world this would (not) be.
