Islam needs urgent reforms. I am from Syria and we have been talking about this for years, years before the crisis of 2011 began. However Muslims simply refuse. They consider any criticism to be an insult.
The Quran has problems. The Hadith has even more problems.
Islam condones stuff like: Polygamy, Slavery, women abuse, child abuse, Jihad to spread Islam, Death for apostasy, the followers of other faiths as second or third class humans (Jizya, Dhimmi), etc.. A lot of Muslims agree on this stuff. For many of them, it is just a matter of capability. Are they able to impose their Sharia law or not? As long as there is a military boot that can crush their necks, they won't dare to demand Sharia law in huge masses, but wait until the security in your country is weak to see them in full Islamic mode. https://www.youtube.com/watch?v=kFqdYRaUH9M
