But my point is that the Sharia court should never be allowed to use force to implement its decision, and death certainly disqualifies.
A Sharia court does not need to proclaim a death penalty. It just needs to decree that "so-and-so is an apostate", and the killing will be carried out informally. Like Theo van Gogh. Like any of a bunch of "honor killings". Things do not need to be spelled out
The legitimized existence of a Sharia court, in itself, constitutes "undue influence" upon all Muslims within its reach
