Few Muslims have shown themselves capable of scrutinising their sacred text rationally
. Indeed any criticism of their religious tenets is taken as an insult to their faith, for which so many Muslims seem ready to kill (as in the Rushdie affair or the Taslima Nasreen affair).
Muslims seem to be unaware that the research of western scholars concerning the existence of figures such as Abraham, Isaac and Joseph or the authorship of the Pentateuch applies directly to their belief system.
Furthermore, it is surely totally irrational to continue to believe that the Qur'an is the word of God when the slightest amount of rational thought will reveal that the Qur'an contains words and passages addressed to God (e.g. VI.104; VI.114; XVII.1; XXVII.91; LXXXI.15-29; lxxxiv.16-19; etc.); or that it is full of historical errors and inconsistencies.
"Why I am not a Muslim
" gives readers abundant excellent reasons for not becoming or remaining Muslims and also makes a compelling case for the conclusion that Islam is flatly incompatible with the establishment and maintenance of the equal individual rights and liberties of a liberal, democratic, secular state.
