People give their lives for all kinds of reasons, including politics ("I regret I have but one life to give for my country..."). Not to mention kamikazes. The fact is that power-seekers have used religious zeal as a figleaf for their murderous agendas throughout history. Nazi ideology had a strong mystical bent which leaned toward pagan religiosity. Hitler had a project ongoing which was to revise the Bible to make him the messiah.
It is a good and legitimate response to the Islamic threat to call into question its religious credentials, in principle, for Islam has nothing in common with any other religion in the world today. It is engaged in wars for territory and power, and unconcerned with the soul. This is a reasonable cause for asking whether it is a religion at all.
People will die for their family and country.
We are talking about Islam being a political movement and not a religion. It most definitely a religion and is the motivation for killing infidels. They don't kill us for family or country. They do it because God(Allah) requires it to be done.-Tom
