Some interesting observations and some thoughts/counter-arguments of my own;
1. Isn’t nationalism a form of collectivism? Coming from an egosit perspective, I owe nothing to the idea of “the nation.” Why should I or others sacrifice themselves to an ideal?
2. The breakdown of religion vs government I would say that they share enough traits in common to be interchangeable. One strives for metaphysical utopia and the other for concrete utopia. Two sides of the same coin really.
3. As far as collectivism goes in general, I see the dichotomy between “collectivism” and “individualism” as fallacious. People are very capable of organizing collectively to meet their needs as individuals (David Grabber raises some good points on the topic of “everyday communism/communalism”). It’s the centralization of economic and social power in the hands of global neo-liberals enforced by the para/shadow governments they fund, but more importantly the concession of the polity that their needs must be met by a third party. A true individualist sees through this rouse and meets their needs and the needs of others by the exertion of will.
4. As you pointed out quite well, ideological crusades across the spectrum that contribute to the problems we see here. Well met.
5. Finally, on postmodernism, as a movement. For one it deliberately eschews labels. It was never meant to replace ideas with any set narrative. It just questions the virtues of traditionalism as well as the meaning and utility of institutions and ideas. It can be violent (it can constitute an outright war on ideology itself. Cautiously embracing metaphysical nihilism and anti-moralism) but it doesn’t justify the substitution of one type of legislated morality for another. The SJW’s who claim that any idea is true and useful by virtue of belief are missing the point (of deconstruction) entirely.
It also produced some brilliant art and literature… food for thought .
