Ah - note the emotions that come up when belief systems are touched upon. I always know when beliefs vs. opinions are in play because of the emotional content of the response.
I'm really not at all interested in opening up belief oriented topics for 'discussion' because beliefs are largely immune to being shifted via conversation, which is doubly true for internet based discussions. That's why we don't do partisan politics, religion, or which 'ism' is the best organizing principle for humans here at Peak Prosperity.
For the record I am not a proponent, hidden or otherwise, for any particular belief based system or stance. I am not quietly working to advance or subvert any one belief based system over another. I think our path forward requires an unflinching look at facts and data and as much rational and conscious thought as we can muster knowing that we have very a active and controlling emotion-based limbic system operating all the time.
If I do have a belief system it's that all the major 'isms' out there are wholly unsuited to the task of usefully organizing humans for the challenge of living sustainably and peacefully within our natural and economic budgets.
With that said, I think it's also important to fearlessly say what you believe to be true and right, and sometimes emotion helps to lift us over the cultural barriers that would otherwise have us sit by politely.
Here are two great examples of that, both of which are well worth your time to view:

Finally, Troof, I would note that your list rather conveniently begins in 1900, which was right after a number of mass mortality events that coincided with capitalism.
For example, the U.S. Native American population in the year 1500 was estimated to be around 15 million but had been reduced to only 237,000 by 1900, making it one of the most sustained periods of genocide on record.
I don't lay that at the feet of capitalism, but at the feet of humans because such regrettable behaviors are the constant in history, not random exceptions that arose because any one particular cultural or economic system was in operation.
Further, I am no longer of the mind that it is only our occasional reckless disdain for each other that deserves our outrage. The reckless ways that we destroy habitats and non-human species are symptoms of the same unconscious drives that ultimately will cost us far more than we seem to be able to appreciate in the moment.
Emotional resilience is, for me, mainly a task of becoming more and more conscious. The first step for me in that process always begins with an act of noticing. I might notice some information in a new way, or simply notice my reaction to something without having the depth of understanding required to really know how it all connects.
If I read Davefairtex's post above on Improving Reality, he uses the same process, where the feelings and emotions that arise are first noticed and then followed as they are a clue that something(s) lurk beneath.
So that's the first thing, noticing.
And it's no more complicated than that. "Hey, look at that, a strong reaction. Hunh."
