Read history Islam is only religion to accept that there are other people of other religions that have rights. Christans refused to accept anyone elses rights except Christans even then they had to belong to their sect. And the only reason that they are accepted now is because of the abandonment of christanity not the application.
In fact Jews and Christans have their own courts in Islamic countries and this is normal. Even know the Lebanon parliment has a Christan member of parliement in the most senior position, second only to the Leader.
Likewise in Egypt there are many christans who make up much of the parliment there.
One of the greatest stories about Islam was when one the rules of Islam Ali ibn Abu Talib was taken to court by a Jewish person and the judge ruled against its own ruler in favour of the Jew! When the Jew heard this then he could believe it, "You are ruling against your own ruler in my favour? Then I am a muslim." He accepted Islam after that.
The Prophet Muhammad (peace and blessings of God be upon him) said, "I will testify against my nation when they oppress those who they have sworn to protect." The people who were under their protection were Christan and Jews.
