The incompatibility of Islamic sharia law with secular courts stems from the underpinning of Islamism — the unyielding union of the laws and punishments of the Qu’ran and Hadiths with the country’s legal and political system. Sharia law is the legislation of these religious and criminal rules, which rejects America’s constitutional secularism and legal penalties.
The Qu’ran commands Muslims to change secular laws to conform to sharia, eventually establishing Islamic law worldwide. Islamic courts want their fatwas to supersede the civil and criminal laws, untying Muslims from civil secular courts.
The facts reveal that in 2008, when the first sharia court was recognized in the U.K., within one year, over 85 recognized sharia courts were established within the U.K.’s Tribunal Court system. The problem with this rapidly spreading dogma is that several of these courts have issued some fatwas that are completely incompatible with British and European law.
As Islam is a male-dominated ideology, the laws of the Qu’ran make half of its devotees, its female population, second-class citizens. This inequality has drawn recent attention to the need for additional British legislation to rein in these courts so they abide by British law.
It appears that once any legal system opens its doors to Islamic law, that door will be hard to close…and eventually, the only thing missing will be a parallel Islamic government.
But even with this reality in front of Americans, there are still many who insist that our laws will prevent such circumstances from ever occurring in the U.S. And because of this nonchalant attitude, there are numbers of people, both Muslim and non-Muslim, who believe that sharia law is not a threat to non-Muslim Americans or to the Western liberal democratic rule of law.
