I have a burdening question in my heart for my Muslim brothers and/or sisters. Is it true, could it possibly be true, that what I read is what the Koran teaches; to kill those muslims who convert to other religions, e.g. Christianity?

Educate me on this because I have not read the Koran at all. If it is true, please explain to satisfy my delicate understanding. Or is this a lie "people" have cooked up against the Muslims?
