Throughout Muslim lands, Christians face persecution, torture and death for "bitterly clinging" to their religion. Apostasy, converting to a faith other than Islam is punishable by death, yet men and woman still convert to Christianity in the Middle East in predominately Muslim countries. Meanwhile, Muslims face no like persecution in the West, and Islam has a tradition of forcible conversion of conquered peoples. (In fairness, Christian kings have also done so, but it is not a tenet of the faith and has not been practiced for centuries.) There is a strain of Islam today that still preaches the imposition of Islam by force.
So I ask, when one religion expands by force and seeks to prevent competition through threat of death and another religion relies upon persuasion to make its case and its believers are unwilling to renounce their faith, which religion is indeed more powerful?
