Islam is a socio-political, socio-economic, socio-educational, socio-judicial, legislatic, militaristic system cloaked in religious terminology. Therefore, Constitutionally, ISLAM should be banned, just like Nazism.
Islam is not like any other religion that goes out, comparing here and contrasting to the Christian faith for instance, and doing missionary work and saying “come and be converted this is a peaceful thing” and so on. No. Islam has always come out and marched and it is conversion by force.
So, it is a political system. When Islam came out from Arabia, it did not go out with missionaries peacefully talking to their neighbors and saying “here is what our prophet Mohamed has come with and so on and so forth. No. There were hordes of assassins who marched into the surrounding world and subjugated them by force.
Islam is a system. And wherever there is a Muslim community there will be sharia. And wherever there is a sharia there is an Islamification of the territory and ultimately of that nation.
