For the most part, the same rage can (and should, IMO) be directed at the very existence of prescriptions in the first place.
If I have any agreement with them, it's in regard to the antibiotics/superbug thing, but I would prefer any number of discipline methods over prescription--and even with prescriptions, I'm sure you can find plenty of such stuff sitting in medicine cabinets (hell, some people probably take them way after the "event" they should have finished them for, trying to combat things.) So, the prescription probably doesn't even do anything there either.
