I didn't label anyone on this thread as despicable. I did label the Tories as despicables on another thread and I see no reason to retract that particular statement.
As to reasons you stated that there might be an increase in illegal booze. Yes there might as there was with ciggies. As I pointed out notwithstanding that illegal trade the effect on tobacco consumption was positive in that fewer people now smoke.
Now, I appreciate that alcohol and nicotine aren't entirely comparable - but I don't see there being that much of a difference if you are trying to persuade people to stop or moderate their behaviour. If you aren't interested in doing that, fine - don't try anything as is Shakers preferred option; or at least he's unsure that there is an option, but at least say so.
