Guess what? There's no turning back if you're born Muslim or a muslim convert. You're stuck with this one and only religion for the rest of your life. Unlike the other religions, the religious practices and choice has always been an "open door" policy, Islam, on the other hand, is strict in the sense that it forbids the conversion to another faith.
As life progresses, it is perfectly normal that we may find content, guidance, faith and peace of mind with another religion and wish to convert. We have the freedom to exercise our choice as long as it doesn't offend others. Apparently, this is not the case if you're Mr. Abdul Rahman. Mr. Rahman is an aid worker in Afghanistan who was arrested and charged with religious offense because of converting back to Christianity from Islam. If Islam is a religion of "peace, tolerance, kindness and integrity" as it claims then there should not be this much of an outcry over Mr. Rahman's personal decision. Instead, educated Islamic clerics around the world should stand up and defend Mr. Rahman's right, not just some selected Christian ministries. Nobody can decide for Mr. Rahman. It's his decision and his rights and we should all respect that.
There's also a similar case in India where Christian converts are constantly being harassed and threatened by the Muslim majority.
