Well I understand that the pacifist 'rebels' on the walking forests world would be a bit like that (though really they should really be more effective in other ways consider ghandi and martin luther king).
They organized a strike once. The stream reveled that you are given an option to bribe or assassinate Ghandi/MLK, and the player picks one. After doing that, the faction never caused trouble again.
But I'm kind of dissapointed neither of the militarists they absorbed used modern freedomfighting techniques, more like the ones they use in HoI, that is terrorism. A more neunced version of it ofcourse more like how we with the benefit of hindsight can view IRA and ETA (Or perhaps even better Gavrilo Princips Young Bosnia) than how we are currently viewing Salafist jihadism.
In fact I find the way that EU4 and CK2 chose to represent rebels kind of boring, it has them line up ti fight just like any other army, this was usually very much not the case, in pre modern times freedomfighters and common brigands were a very blurry line, in more modern days terrorism has mostly taken the place of those activities (but not entirly, for an example several south american freedom fighting groups kidnapped westerners for ransom to fund their war).
Keep in mind that something distinctly "modern" is more likely than not to be historically anomalous; if it is particular to our time in the history we know, occam's razor suggests that it is particular to our time in the history that we don't know as well. The evidence that we have available to us in this time also suggests that terrorism is not a very effective way to achieve victory, but only to prolong conflict. Keeping that in mind, it makes sense that it wouldn't still be a major way of fighting in a future historical period.
Another good example might be the United States. The parts which are most ethnicity diverse (California, New York, Chicago) are also the safest, most advanced, most stable and richest (once you factor out resource-extraction wealth.)
From context I don't think you are, but this is wrong enough to seem sarcastic. "Safest" is definitely not true (Chicago especially is renowned for its murder rate) and "stable" is meaningless with regard to a state within a greater nation which hasn't had a notable rebellion since before the population patterns you're talking about were established. And "most advanced" is meaningless in general while "richest" is more likely a cause of diversity than an effect.
You're right that that wealth leads to diversity, but it is also true that diversity leads to wealth. Both of these factors contribute to one another. Wealth and dynamism attract people from all across the world; most of these people will be those who had the motivation and determination to leave their birthplace and find new homes. As a result, they foster an even more creative, dynamic atmosphere.
There's a reason why I no longer live in South Africa. The brain drain is a real thing.
"wealth attracts diversity" is a clear and obvious fact. "diversity attracts wealth" is not necessarily, and all you've actually argued in support of it is "education attracts wealth" which isn't the same thing.
As for the whole xenophobia vs xenophilia is productive argument, I think is coming from the wrong angle. It is economically growing and abundant that tend to grow more xenophilic and welcoming, whereas stagnating or collapsing economies grow more xenophobic. It is more apparent for the ones hit hardest by economic downturns who always find something to blame, that someone is often a xeno. It also worth noting that this is all from a human perspective and there is no gaurantee it will hold true for aliens.
This is true, but Stellaris is built on the paradigm that ethos effects societal conditions, not that societal conditions effect zeitgeist.
Right, but then they're absurdly kind and peaceful, so they would never enslave, meaning they would have to be neutral...but then this wouldn't reflect their isolationism, which requires "xenophobia".
So I have to conclude that they simply could not exist in Stellaris as it stands (or the closest approximation would be fanatic pacifist spiritualist, leaving xenophobia/philia on neutral).
I hope that ethos's will be reworked somehow to allow such a species to be better reflected.
To be honest, I see that system becoming a lot more deep in the future anyway, to allow for races to have more character (more ethos choices and higher limits). I can see a major rework on the horizon once we've all played the game and provided feedback to Paradox.
I've mentioned this before, but the amount of ethos points is actually very limiting, one more would unlock a wealth of other options. And Xenophobia/Xenophilia is a very shallow and specific take on the philosophies which it attempts to emulate, a problem not really in common with the other ethos options.
I think you need to go back and research the gang activity in LA, Chicago and NYC. In the case of Chicago, its about as bad as it gets. I personally work as a firefighter in California and deal directly with Mexican gangs that are supported by the Mexican mafia - drug trafficking. This is no Shangi La here.
Also, the diverse population here is stratified by wealth. ie...minorities are mostly poor. The richest Hollywood executives are all from the same ethnic group - and almost exclusively male. The other big industry in California is military weapons production. I wouldn't exactly characterize this situation as "xenophilic".
You're forgetting the tech industry, which does include some amount of women, and makes often hires minority ethnicity as long as they cleave to the correct culture (which is more a culture of wealth and a certain background than an ethnically defined one, despite being majority white). Also technically not all of the top Hollywood guys are the same ethnicity. The number one richest movie mogul (George Lucas) is not even Jewish, nor is James Cameron (number 10) though all the ones in between are (and apparently all ashkenazi specifically). And the word "mogul" itself makes its way to the English language from Jewish...
I do think we're rather off topic by now though.
