Wowsers never miss a chance to call for tougher laws and sentences when it comes to trying to restrict access to the evil drink. Now their reaction to the perfectly reasonable throwing out of the discrimination against 18 to 25 year olds when it comes to buying alcohol (they are the only group in society that needs to carry compulsory ID when they want to buy a beer) is to institutionalise the discrimination.
I could only agree with compulsory ID carrying if it applied everybody, and not based on your age or any other arbitrary criterium.
Also, I think a doctor prescription, with a second independent medical opinion, should be mandatory for any man over 40 wanting to buy Viagra. If the game is to restrict access to lifestyle drugs, the example should be set at the top.
