You obviously don’t know what Islam is and naively assume it is like other faith-based religions. Not surprising. However, in stark contrast to faith-based religions, Islam unique in the world is a religion of submission where the freedom of conscience is forbidden under the pain of death and whereby all Muslims must submit to the will of Allah, i.e., Sharia.
For instance, as an adherent of a faith-based religion I can freely pick and choose what it is I will believe and what it is I will reject, and I can even freely choose to leave the religion if I so desire. However, if I were a Muslim, on the other hand, I have no choice in the matter since in effect I’m a slave of Allah. Hence, if I so much as question the tenets of Islam that would be construed as blasphemy, and blasphemy is a serious offense in Islam that is punished under the pain of death. Furthermore, as a Muslim I wouldn’t be able to freely leave the religion of Islam if I so desired, as murtaad (apostasy) is a serious offense under Islam that is likewise punished under the pain of death.
In Islam, you are either a Muslim, i.e., a slave of Allah, or otherwise you are the infidel, and, of course, if you are the latter then you must be killed.
But religion isn’t all that Islam is. Since with Islam you also get Sharia, as Sharia is intrinsic to Islam, Islam is a very radical form of totalitarianism that seeks world domination as its main goal. Indeed, Sharia institutionalizes systematic persecution and often violent oppression of females and non-Muslims and incorporates draconian punishments such as lashings, stonings, beheadings, and amputations, while forbidding the freedom of conscience, the freedom of speech, and the freedom of religion, at the same time it also mandates death to apostates. In addition, Sharia commands all Muslims to wage offensive jihad for the spread of Islam via the imposition of Sharia, and this mandate to wage jihad for the spread of Islam is the sixth pillar of Islam. Hence, if you take Islam in totality for what it really is, far more than just being a religion alone Islam in fact is a totalitarian theo-political ideology that seeks world subjugation via the imposition of Sharia.
Therefore, because the obligation to wage jihad in the cause of Allah for the spread of Islam is the sixth pillar of Islam, all devout Muslims that are capable must adhere to that pillar. However, as I previously stated in previous posts, jihad can be both violent and non-violent, stealth, and deceptive, which means it can be as non-violent as just giving zakat or as violent as being a suicide/homicide bomber.
Finally, the vast overwhelming amount of jihad that takes place in the world today takes place for the most part behind the scenes via non-violent, stealth and deceptive means, and for a good example of stealth and deceptive non-violent jihad in action, let’s take a look at Western Europe. In Western Europe wherever mass Muslim immigration is occurring we see the vast overwhelming majority of Muslim immigrants instead of assimilating and integrating like other immigrant groups, forming Muslim no-go zones instead ruled by Sharia in direct contravention to the laws of the states in which they reside. This form of non-violent stealth jihad is known as demographic conquest, and it provides documentation per your request.
