Indeed. And some examples in Europe.
But it's the interpretation of the politics of religion by many Moslems which needs changing. There are thoughtful, peaceful Moslems, but the religion also keeps inspiring people to do harmful things. Most of these harmful acts are founded on an aspiration to convert or control the societies in which Moslems find themselves - to make them obedient to Moslem rules. To encourage submission to Islam. Not surprising since this was Mahomet's aim also, whether he was in Mecca or Medina.
The answer of the vast majority of Moslems to the question - does Sharia have a major role in law and politics - needs to be "No". Same as the answer to the question - should church law have a major role in law and politics - is clearly "No" also. In the West, law and politics are a secular matter. The church may cajole and talk about morality. But we don't follow a fundamentalist model of church as lawmaker for society using biblical texts. Everyone, except the ignorant, agrees this. It was resolved in the US in the Constitution. The church only regulates itself.
The Christian church no longer has aspirations to turn the political sphere into a religious domain. These battles were fought long ago over things like the imperial papacy, the investiture of bishops, the sale of indulgences, church taxes (Peter's Pence), the interpretation of the heavens and the origin of species. Folks like Thomas Aquinas recognised the difference between divine law and human lawmaking. Charles Darwin described a mechanism by which life evolved and that didn't require divine intervention in the temporal world. The two paths forked long ago in ways that most people have long forgotten.
In the end, religion ended up a matter of personal choice and not of universal politics or the foundation of law. Law is created by people in relation to their circumstances. It is written and we write it. Secularism prevailed. In the USA, this is expressed as a principle in the first amendment. Clearly the founders were aware of this issue (even if Jefferson made the mistake of defining a Creator into the foundation document of the US).
So we need this acceptance within Islam also. Doesn't seem to be an issue within other religions for whatever reason.
