I'm not sure how you arrive at these conclusions. Ethics need not be a part of ideology, and even if ethics are part of an ideology, that doesn't make ethics an ideology any more than a car part is a car. You're committing the fallacy of composition, in other words.
I arrive at these conclusions based on perfectly standard usages of the terms ethics and ideology, and I
specifically said ethics is
a part of ideology. You are committing the fallacy of not reading posts before replying to them
Ethics is about ideals: your principles about way people should behave; moral correctness
Ideals are part of ideology
But what I said is that I don't categorize people as good or bad. How is that an ideology? It's actually a lack of ideology. My effort to make people as well off as I can is more of a practice than an ideology, and it's not based in any religion or political or economic system. So it's more of an ethic than it is ideology.
These are ideological principles, they are not "an ideology".
And if you think we should make people as well off as we can is neither political nor economic in nature then you might want to look up those terms too...
Politics (from Greek: Πολιτικά, politiká, 'affairs of the cities') is the set of activities that are associated with making decisions in groups, or other forms of power relations among individuals, such as the distribution of resources or status.
Economy: In general, it is defined 'as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of scarce resources'.
But seriously, you make a lot of condescending assertions. Moreover, I simply have no ideology. That's a fact.
Not my fault you can't understand what ideology is, and thus operate under the conceit that you are a unique cognitive giant who transcends the cognitive needs of lesser mortals.
You can lead a horse to water...
If your experiences and education led you to adopt your ideology, then those are the true factors in your thinking and behavior, not your ideology. Your ideology is just a way to explain your way of living.
What I said: combination of: where I grew up (culture), my family and friends and socialisation, my experiences, my education, ideas that I read or heard about and evaluated with rational thought rational thought, irrational biases and prejudices, rationalisation of that which I can't change, etc.
It is a dynamic process
Humans don't see the world neutrally, we are biased by all kinds of cognitive factors. Many of these are based on the experiences, education, biases, education, etc. of other people we come into contact with.
Our ideology is a sum total of a diverse range of influences, that in turn influences how we interret new information and experiences.
It is partly consciously adopted and part beyond our control: we cannot fully transcend our cultural environment, etc.
So getting back to Stalinist Russia and Hitler's Germany, people in both places lived under circumstances that caused them to violently lash out at their perceived enemies. Note that very similar behavior was rationalized by very different and even adversarial ideologies. In other parts of the world many people knew well Bolshevik and Nazi ideology yet did not commit mass murder. Logically, then, it looks to me that what caused the bloody violence was the conditions people lived under rather than the ideology.
Again you confuse
knowing an ideology from
accepting an ideology.
As I've said, we can look at many examples from history that show the kind of conditions that violent, millenarian ideologies are most likely to arise from.
We can find far more examples of these conditions being present without mass, utopian violence breaking out.
Plenty of people have lived in far worse conditions than the Germans and not handed their country over to a genocidal, totalitarian regime. The USSR under Stalin was wealthier than under Lenin, but more violent. Plenty of upper-middle class Muslims from rich countries joined ISIS. The idea that it is just 'bad conditions' alone that drive such behaviour is obviously nonsense.
Hence:
Once we have millennia of abstraction, human instincts no longer have any necessary connection to reality. You may "instinctually" hate Jews, simply because of what you have read other people say about them, which they made up because of what other people made up, that they made up because of what other people made up, and what they made up because of the Protocols of the Elders of Zion which was made up.
Trying to understand German anti-Semitism purely through the lens of "instinct" without recourse to ideology would not be meaningful. The key point is how ideology 'manipulates' human instincts that evolved to be focused on survival, not discerning objective truth via rational evaluation of evidence
Abstraction starts to separate experience from reality. So in a small group, it would be hard for me to judge Saul to be a bad person if they had always been kind to group members and diligent in group endeavours.
Fast forward to Germany in 1939.
Fritz, Hans and Herman know no Jewish people. They are all from the same town, went to the same school and are all upper-middle class.
It would be perfectly possible for them to hold these views:
Fritz thinks Jews were just as good as other Germans and finds it terrible they are being oppressed by fanatics.
Hans thinks Jews are infidels who killed Jesus and that unless they convert to Christianity, they cannot be true Germans. If they do convert though, they are as good as any other Christian German.
Herman thinks science has shown Jews to be genetically inferior and finds the idea they will pollute pure German blood to be sickening. He believes Jews can never be German and they must be removed from Germany once and for all before it's too late.
All of these ideas are purely abstract, have no connection to directly experienced reality and may even be objectively wrong.
The hold different ideological views because of genetics, intelligence, upbringing and socialisation (family and friends), exposure to events, vicarious exposure to events (friends, media, etc.), exposure to abstract ideas (friends, books, media, educations, etc.), rational thought and argumentation, etc.
It is also perfectly possible that any one of them moves from their current beliefs, to adopt any one of the others.
You seem to be suggesting that it wouldn't matter which one of the ideologies they adopted, it wouldn't actually influence their behaviours in any way.
