It is. There are plenty of more or less practising Muslims who behave perfectly well and are strongly opposed to theocracy. In the same way that there are plenty of white Christians who don’t feel the urge to take a gun and mow down blasphemers.
> And second won't work because Shariah law gives very concrete directions on dealing with non-believers.
It’s a false dichotomy. Lots of Muslims do not believe that Shariah law should be applied. On the Christian side there have been debates for centuries about this sort of issue, and pretty much nobody believes that the laws in the Old Testament should be applied or have any relevance nowadays. By painting the whole of Islam as being one simple shade of fundamentalism, we contribute to making the situation worse. People need to realise that there are old Muslim traditions that don’t advocate for stoning people, and that what we take for standard Islam is the creed of a particular cult and not universal.
