I'll make some short points, all of which can be easily verified by the most cursory of Google searches:
* The European Court of Human Rights has determined that "sharia is incompatible with the fundamental principles of democracy."
* The Islamic Republic of Iran, Egypt, Pakistan, Saudi Arabia, the Sudan, Syria, Bangdalesh, Iraq, and Afghanistan have jointly lobbied the United Nations to make exceptions in the application of the Declaration of Human Rights, to accommodate the practices of muslim nations.
* These same nations also have also petitioned the United Nations for exemptions from the rules of Freedom of Speech, in regard to what sharia law considers blasphemy.
If you are too lazy to look up the issues yourself, Wikipedia is always and easy and reasonably reliable reference for major topics:
