No isolated act of extreme violence will cause *anything* to happen in the masses but what their accepted social environment dictates.
So the goal is to change the social environment, called often the Overton Window or the Zeitgeist, and anons are lucky because it's exactly what they do best: Redpilling people. No garden ever grows properly on untilled soil.
The first step, detailed in first-hand experience from just about every user and in many books, is to get people to notice the problem. Noticing is the first and most important redpill. Noticing lets people see that Muslims now are ruining their countries. Noticing lets people see (((who))) are promoting the decay of their values and societies. Noticing lets people see the lies they have been fed and the absurdity of what has been blasted to them from above by those who want to treat them as slaves and cattle.
It is that noticing that allows anons to look at this recent spectacle from Tarrant in a different way than the non-redpilled public. Without that there is no hope in hell of getting a beneficial reaction from the populace. Tarrant's mistake was thinking that pointing out that "Christchurch" was now infested with Muslims, the very antithesis of Christianity, would affect the general populace in the same way as him. He was redpilled, the populace was not. This lack of cultivation beforehand means that his action will more or less trigger the normal pathologically tolerant responses in people rather than the Deus Vult response that he desires. It does not serve as a good redpill in itself because the violent spectacle overwhelms the message that Muslims are conquering the dying spirit of the Western man without a struggle. The average Western person's spirit is so weak that they see the destruction of a foreign body as infinitely more important the the destruction of the soul of their own people.
What would have been more effective was to show Christchurch, in fact many more churches like it, succumbing to the Muslim's soft invasion. Showing people the rotting out of the spiritual cores of Western society, the gloating and intentions of those who did so and those who opened the gates to them, and engaging the emotions of the target audience over that matter would work for redpills. The entire message that convinced Tarrant for instance was first through beginning to notice things through redpills and events that allowed him to see a problem as a problem, not from a partisan striking back against seemingly harmless brown people. Muslim attacks on White societies works to allow redpills only in that it disrupts that messaging and, in that confusion, allows for alternative ideas to take root once the dust settles and they can't properly reconcile it.
The reason why this redpilling process is frustrating to some is that when it is working it appears like nothing is happening at all! The real redpilling happens behind closed doors, late at night, where men stare up at the ceiling and wonder quietly to themselves, "Is what I have believed all my life actually true?" It's like The Man Who Planted Trees, with redpills sown about where only some take root, and the process is so subtle and so gradual that when the forest eventually springs up everyone believes it is a spontaneous miracle rather than the efforts of some persistent and dedicated sowers. Western society needs that forest to be growing properly before the right actions can be taken - actions that are far less violent and far more effective than what Tarrant and those of his opinion can offer today.
Right now that forest is growing in the hearts and minds of many people. But they are obviously not ready yet to see events like Tarrant's to be anything but what the (((media))) tells them it is. More redpills need to be sown and cultivated. It is not the foreigners or brown people that are causing this paralysis in the Western spirit, but ourselves and one another.
But the time for violence is not now. We haven't even truly begun to stand up and speak out of fear of one another's scorn, so it is utterly absurd to believe it is time for physical violence. If you want to do something revolutionary, speak. Speak to your people and tell them what you have noticed. Stand up if you have the courage for it and be a beacon of reason and hope for those who let fear guide them to slouch and moan in the shadows. Shitpost the enemies of the West, laugh at the tyrants that wish to rule over you, and distribute the ideas that will supply them with many thoughts during those sleepless nights. Those are the soldiers we need now, not partisans or vigilantes.
