I don’t think the word collectivism means what you think it means.
Islam lived by plunder, taking other people’s stuff away from them. Much as the Roman Republic and Empire did. And the robber barons of the Middle Ages, etc.
That’s a very different concept from collectivism.
Noun
The practice or principle of giving a group priority over each individual in it.
The theory and practice of the ownership of land and the means of production by the people or the state.
Islam is about establishing Muslims as a ruling class over the rest of us, not about collective ownership by all.
A scholar! :) I was stretching the definition I suppose to apply it in the fashion that Ayn Rand would. Rand would have called it the use of force to loot the productive work of others. But I recognize your correction. My main point is that Islam created a class culture based on bigotry, whereby non-Moslems represented an underclass. This held true in the Soviet Union, but the underclass in that case were the farmers, who were expected to feed the working class. There is the definition of collectivism, but in practice the “people” never really benefit.
