Be muslim but reject the political program of islam (no sharia), make islam a personal religion (as all other major religions). Only secularism and modern democracy work.
Sharia was definitely not conceived to give equal rights to all people:
" People of the Book were not permitted to show any disrespect toward Muslims or animosity toward Islam, the prophet himself or the Quran.
If a Jew or Christian were sitting by the road and a Muslim walked by, the Jew or Christian must stand in respect to the Muslim.
If a Jew or Christian were walking on the road, and he met a Muslim coming from the other direction, the Jew or Christian must turn around and find another road to walk through.
People of the Book were not permitted to ride horses. They had to ride donkeys, and the Muslims could ride horses.
People of the Book were required to ride their donkeys sidesaddle (not with one leg on each side of the animal as the Muslims did on their horses).
People of the Book were not allowed to build their houses higher than the Muslim houses. (The height of the house was important because it was a symbol of honor. Muslims were always supposed to be above non -Muslims.)
People of the Book were not allowed to drink alcohol in front of Muslims. They could drink alcohol in their houses, but they could not appear drunk outside their houses where Muslims could see them.
Christians were not allowed to let Muslims see th e pigs that they were raising. The pigs had to stay hidden.
Christians and Jews were not allowed to bury their dead during the daylight where a Muslim might see. They had to take the casket quietly at night to the cemetery and bury it. They were not permitted to cry for their dead in public where a Muslim might see or hear them.
In the Jewish synagogues or Christian churches, people were not allowed to raise their voices loud enough to be heard outside the building.
The Muslims did not want to see or hear People of the Book practicing their religion or their holy days. People of the Book could not cele brate in public.
People of the Book were not allowed to try to convert Muslims away from Islam.
People of the Book were prohibited from serving in the Islamic military.
People of the Book were not allowed to help anyone declaring war against Muslims.
People of the Book were not permitted to carry weapons.
People of the Book could not testify against a Muslim in court.
A Muslim could not be killed because of a Christian or Jew. In other words, if a Muslim killed a Jew, he could not be punished by death for that crime. (Muhammad said in hadith, "A Muslim believer cannot be killed for an infidel.")
People of the Book had to wear special clothing and special colors that identified them as non-Muslims. Christians wore blue; Jews wore yellow; Samaritans wore red . Both men and women wore these colors.
Christian women had to wear a sash around their waists.
Christian and Jewish women had to wear shoes of different colors. In other words, the left shoe had to be a different color than the right shoe. They had to wear shoes that didn't match!
Christians were not permitted to enter any public place without wearing a large cross around their necks. It had to be made of metal, and it needed to be heavy enough to be uncomfortable, probably about two pounds."
and so on...Many of these ceased to be applied now indeed but the remnants of sharia, regulating the behaviour of non muslims under muslim rule, survive and discriminate, just look at the 'muslim paradises' worldwide. Finally the mere fact that non muslims have to show unbounded respect to the irrational taboos of islam*, although allegedly they do not have to follow sharia, is discriminatory. That's why sharia has to disappear altogether from any modern Constitution (more generally it must not influence the laws); at most parts of it should be allowed (not in the Constitution of course) for people who accept it (rulings not binding and depended on voluntary compliance), those fully compatible with modern laws and principles...
*this will be valid even in the fantasy worlds of the so called muslim progressists who still insist with sharia influencing legislation
