Thanks for answering this question.
You see Muslims believe that Islam is the truth and some are happy to lay down their lives for this cause.
I am of course talking about in normal circumstances killing innocent people is condemned in Islam.
Also Muslims are encouraged to follow the everlasting example of the Prophet Muhammad (peace and blessings of Allah be upon him). This helps us put into practice the holy text of the Muslims the Quran.
So the religion and its rules are made clear for us and for us to change them in itself is almost heresy.
The point that you are trying to make but stop short of, is that Islam must be the truth otherwise why would someone refuse to compromise on his beliefs. The way in Islam is clear, really clear.
If you would like to ask me anything please email me. I really liked your question and your honesty.
