Religion is tricky business. That is why our Constitution tells us not to establish a government religion. Not a freedom from religion, but freedom of religion. Being that it doesn't impose on others a loss of their freedom. Everyone is free to believe as they wish. Very wise. This country is based on free will choice. It is because of Christianity that we enjoy that freedom. But Islam in its pure form is not compatible with our Constitution. It requires conversion. I don't believe that should be celebrated by our government.
According to Abdul Rashied Omar, the majority of modern Islamic jurists continue to regard apostasy as a crime deserving the death penalty.[13] Some regard apostasy in Islam as a form of religious crime, although others do not.[5][6][19] Others argue that the death penalty is an inappropriate punishment,[20][21][22][23] inconsistent with the Qur'anic injunctions such as Quran 88:21–22[24] or "no compulsion in religion";[25] and/or that it was a man-made rule enacted in the early Islamic community to prevent and punish the equivalent of desertion or treason,[26] and should be enforced only if apostasy becomes a mechanism of public disobedience and disorder (fitna).[27] According to Khaled Abou El Fadl, moderate Muslims do not believe that apostasy requires punishment.[24] Critics[28][29] argue that the death penalty or other punishment for apostasy in Islam is a violation of universal human rights, and an issue of freedom of faith and conscience.[20][30]
As of 2014, laws in various Muslim-majority countries prescribed for the apostate (Arabic: ????? murtadd) sentences ranging from execution to a prison term to no punishment.[31][32] Sharia courts in some countries use civil code to void the Muslim apostate's marriage and to deny child-custody rights as well as inheritance rights.[33] In the years 1985-2006, three governments executed four individuals for apostasy from Islam: "one in Sudan in 1985; two in Iran, in 1989 and 1998; and one in Saudi Arabia in 1992."[25] Twenty-three Muslim-majority countries, as of 2013, additionally covered apostasy from Islam through their criminal laws.[34] The Tunisian Constitution of 2014 stipulates protection from attacks based on accusations of apostasy[35]
