Sorry to say, your information on the matter of Al-Quran and Shariah is totally absurd and rotten with a flavor of western view on Islam.
"An Eye for an Eye" applies everywhere,Voilence of any type is in every religion Including the epics "Ramayana" and "Mahabharata".
I have many convert friends who were HINDUS but now are MUSLIMS and i am ashamed to be a kind of muslim that i am.They are 1000 times better than i am. The answers to your questions can be obtained only by you .
Please try to go thru the Al-Quran( translation ) once and then point a finger at it. Muslims now adays are "Astray" and do not represent "Islam" as it should be.
If Islam is what u think it is, then there would have been no converts like Yusuf youhanna, Cat Stevens(yusuf Islam), Kamala das,Mohd Ali(cassius clay) or...... Sorry if i am anyways hurting you.
But, One cordial request Please do not blame my religion but blame me and thousands of muslims like who are unable to present "Islam".
Islam cannot be understood by mutual email debate but by acknowledging facts. which are there and universal. Please do get back to me for some querries and of course to be my friend...
