I don’t consider myself Right Wing (I don’t even know what it is supposed to mean). So to answer your question, I don’t support Sharia Law or its penalties for two reasons: (1) because such measures have not been approved by the UK Parliament and (2) I am not looking for retribution in criminal sentences. There are four objectives to sentencing (in descending order of importance in my opinion): punishment, protection for the public, reparation and rehabilitation. So instead I call for robust penalties commensurate with the seriousness of the offence, the circumstances of the offender, and sentences aimed at achieving an appropriate mix of the objectives above. Penalties under Sharia Law seem to provide none of these..
There is a deal between the State and the people whereby individuals will not take retribution on people who commit crimes against them and instead the State will provide appropriate punishment on their behalf. For this deal is to be worth its salt the people must be confident that the penalties provided match the crime committed. In recent years sentencing guidelines have suppressed penalties and the police have taken to issuing fixed penalties for repeat and serious offenders, The “deal” is being broken but Sharia Law and its penalties are not the answer.
