Those who, stand either individually or in clumps, claim that they are defending Islam do not trust in Allah and thereby blaspheme. These people are of narrow minds and materialistic creed. Let us consider some of the more relevant and obvious repercussions of accepting Allah as the "The Originator of the heavens and the earth!" (Surah 6:101) which is basically this Universe, and the many billion other universes out there, all that space, and clutter in between. We, in truth, don't even make up an atom of a grain of sand in the entire scheme of things. And those are just His creations - so, in truth, we will never be able to even comprehend Allah. Whoever claims they do, makes false claims for godhood. And therefore sins.
Let us consider this starting point: that we are unfathomably small in His entire design. We die out just like all other living things on this earth. Our lifespan is short - a maximum of just over one hundred - with an average of about late 60s these days. We, as Homo Sapiens, only arrived on the scene relatively recently i.e. about 400,000 years ago, and our recorded history only stretches back to about 32,000 years ago with those cave paintings in Chauvet Cave of Chauvet-Pont-d'Arc Cave, in southern France. The earth is estimated by scientists to be approximately between 4.5 - 6 billion years old. So that's how we are even compared to the earth. Nothing much. And the universe? Scientists currently estimate it to be about 13.7 billion years old. So in terms of times our Homo Sapien race existence compared to the universe - our significance is 0.0000029197080. Now you then divide that but all the many people, animals, etc. and you come through and we realize how insignificant any of us are.
When seen in this light, that Allah was long before us and shall be for ever, so what does it matter if some of his most insignificant creations on one of His billions, if not trillions, of galaxies and planet, does not believe in Him? What does it matter that there are these non-believers who speak ill of Him? The truth is that no one can harm Allah or his religion because we are in His realm. What is more, going by scripture, we are all answerable to him on Judgment Day, so why should we have to answer to someone lesser whilst we are alive? A comparative analogy of the relationship between Allah and mankind/His Universe would be as a computer programmer to his program. Whatever program a programmer programs into his computer can never harm him (assuming it is your usual standard desktop PC and not some robotic killer machine whose sole purpose is to annihilate any living thing) - he can manipulate it, change it, do virtually anything to it but the computer or its programs or the product of its program can never, ever harm the programmer. So when there is no threat, there cannot be a defence.
And Allah is Eternal and Creator of All - what possible threat can there be to the Supreme Being of the Universe? If even Satan himself cannot bring about such an event (because he will get his butt kicked in the End of Days), then what more the mere sons of Adam? And what do these ants think they can do in Allah's defence? That some of his sons thinks that Allah is in need of protection is to betray what they really think of themselves and Allah. The first is that they think too highly of himself and his worth to the Allah and the Universe and secondly, they think too lowly of Allah and his Creations. They do not say this explicitly, but there is no need to because actions have always spoken louder than words.
So what is this Defence of Islam really about then? It's the same thing that has happened over the centuries where religion is concerned: frustrated, unthinking, unlearned, morally and ethically corrupt human beings who want to achieve some control in his life and do so by piggybacking on a religion to establish a high moral position and to burn with righteous anger with supposed authority from God with which he can then carry out his psychosis. This Defence of Islam strategy is an attempt to play up their victimhood (defence presupposes an attack) to try and attract sympathy from unconcerned or unrelated parties. But then in banding together and claiming defence they then allow themselves the possibility of a pre-attack strike (because that is a defence too which America used as a justification in attacking Iraq). Ultimately, the entire strategy is geared towards confrontation and violence.
The truth of the matter is that the Defence of Islam was never about Allah. It was always about the corrupt Muslims who seek not to worship Allah in humility but to try reach His exalted status; and then in failing so miserably and ending up no better than Satan and his cronies, end up ultimately becoming a disgrace both to Islam and Allah.
