I have sometimes heard reasonably intelligent people speak in favour of Sharia Law - because it is not afraid to punish.
We are not simply talking here about the restoration of capital and corporal punishment Singapore-style for grave offences.
There is rather more to it! (What should the penalty be for a Muslim who converts to Christianity, for example?)
For those who make sweeping statements based on very little actual knowledge - a little more thought is perhaps called for.
