I’m not exactly sure why you went off a tangent like that.
Here you belittle people for being liberal, yet clearly you hold modern Western values, not historically rooted in Christianity. Modern Western values, that were initially fought against by the Church might I add (see counter-enlightenment).
Politics is only a secondary part of Islām, not a fundamental part of it. If it were fundamental, then Prophet Muhammad from the get go would have strove to establish an Islamic State, but he didn’t do so; thoroughout his mission, he was a part time judge, a part time military leader, a part time diplomat, got involved in social issues from time to time, but he was never a political leader. In a famous tradition, when given the choice between being Prophet-king or Prophet-servant, he chose to be Prophet-servant.
By that token, you must not believe that Jesus is the God of Moses. Even if the Old Law is no longer in effect, it doesn’t change what God commanded in the Torah (Deuteronomy 13.6-11):
“If thy brother the son of thy mother, or thy son, or daughter, or thy wife that is in thy bosom, or thy friend, whom thou lovest as thy own soul, would persuade thee secretly, saying: Let us go, and serve strange gods, which thou knowest not, nor thy fathers, Of all the nations round about, that are near or afar off, from one end of the earth to the other, Consent not to him, hear him not, neither let thy eye spare him to pity and conceal him, But thou shalt presently put him to death. It Let thy hand be first upon him, and afterwards the hands of all the people. With stones shall he be stoned to death: because he would have withdrawn thee from the Lord thy God, who brought thee out of the land of Egypt, from the house of bondage: That all Israel hearing may fear, and may do no more any thing like this.”
It may interest to know, that there is no death for apostasy in the Qur’ān.
“Neither shall the wicked dwell near thee: nor shall the unjust abide before thy eyes. Thou hatest all the workers of iniquity: Thou wilt destroy all that speak a lie. The bloody and the deceitful man the Lord will abhor.” (Psalm 5.6-7)
“Walk not after the laws of the nations, which I will cast out before you. For they have done all these things, and therefore I abhorred them.” (Leviticus 20.23)
“Six things there are, which the Lord hateth, and the seventh his soul detesteth: Haughty eyes, a lying tongue, hands that shed innocent blood, A heart that deviseth wicked plots, feet that are swift to run into mischief, A deceitful witness that uttereth lies, and him that soweth discord among brethren.” (Proverbs 6.16-19)
