Islam is a governmental system. It is a totalitarian system that dominates every aspect of daily life. It is tyranny on steroids. The religion that Islam allows is Muslim. Muslim is a religion, but only able to exist if Islam is the system of government.
Muslim cannot exist without Islam to support it and Islam cannot exist without Muslim followers because neither one allows for any freedom or questioning or individuality. The Muslim faith MUST have a legal system (Sharia) and governmental system (Islam) that will enforce its religious practices or else people will question its practices and many will no longer abide by them. Islam MUST have Muslim believers because without them the government would have too many people questioning its tyrannical hold and dominance over them and many would rise up against that government.
Christianity existed long before there was a USA constitution and without Christianity, the USA would still be able to maintain its legal system and government. The USA does not need world dominance to exist and remain strong on its own. The USA was founded mainly on Christian teachings, but it would survive with Jewish, Buddhist, Daoist teachings just as well. Islam cannot do that, which is why they continually try to force Islam on every living being.
If there is even one person who does not submit to Islam, Islam is imperiled because that one person would be the weak link in their chain of dominance. The human spirit always seeks freedom. That will always be Islam’s weakness.
