I don't know how hostile I am to your idea that ideology can create monsters out of peaceful people. I just see it as the nonsense that it is.
The ability to commit violence in defence of the in-group is evolutionarily advantageous. I'm sure you must agree with that.
Given this fact, it's ludicrous to think that good people cannot be convinced to commit violence on behalf of the in-group when we have millennia of evidence to show otherwise.
"Sometimes we commit atrocities not out of a failure of empathy but rather as a direct consequence of successful, even overly successful, empathy,"
Does Empathy Have A Dark Side?
The violent tendencies come first and when acted upon the violence is excused with ideology. That's what I've been arguing all along, and I'm glad to see you're getting it.
Don't be silly. Violent tendencies exist in all humans. We aren't all automatons though.
As to which drives violence, it's a dynamic process.
Ideology does develop from a combination of environment, experience and individual and group psychology, and it in turn influences environment, experience and individual and group psychology.
Mass coordinated violence doesn't come from lots of people simultaneously deciding to commit random acts of violence then retrospectively agree to concoct an ideology to justify it though.
Ideology binds people into a group and tells people what is required to be a good group member. If what is required to be a good group member is violence, then it makes people more likely to commit violence.
The ability to bind people into ever larger groups and have them take individual risks and commit violence in the cause of the group can obviously be evolutionarily advantageous.
Your argument that ideology is simply after the fact rationalisation that plays no actual causative role in behaviour is clearly wrong.
If "internet speculation" doesn't count as having scientific validity, then why should anybody pay any attention to what you say? Besides, the material I posted about the mental illnesses of Stalin, Pol Pot, and Mao is legitimate science.
Forum posts are not science, so have no scientific validity. They are for entertainment.
Speculating about the mental health of people you have never met let alone clinically examined is also not science. It is journalistic speculation.
I didn't say that culture can make people hostile toward other groups; rather, hostility toward other groups creates ideology
And then may drives further hostility and exponentially increase hostility.
There's a big jump from being prejudiced against Jews to carrying out the holocaust.
A small group of extremists can very much change society by spreading their ideology.
The roots of the holocaust go way back long before Hitler and the Nazis as I've just documented. Martin Luther, as another good example of such a root, became angry with the Jews when they refused his attempts to convert them. (Does that sound familiar?) His outrage led him to write his "On the Jews and Their Lies" treatise in which he advocated for the persecution of the Jews. As many historians have noted, Luther's anger toward the Jews led ultimately to the Nazi's genocide upon them.
Anti-semitism has existed since pre-Christian times. Simple prejudice tends not to lead to genocide though.
Luther was obviously Anti-semitic, but despite his bigotry wanted Jews to convert.
Nazi anti-semitism was based on scientific racialism, which is why even Christian "Jews" or atheist "Jews" were still the enemy.
The final solution was based on this racialist idea of Jewishness, and its potential to "pollute Aryan blood". There was no room for "convert or else" in this ideology. No escape route.
Religious anti-semitism is very bad, but "scientific" racialist anti-semitism is worse.
Ideology matters.
(lots of "good people", liberal and progressive men of science, believed in racialism and eugenics btw. It was "rational" a bit like believing in climate change is today. They didn't know they were wrong and their beliefs would later be deemed pseudoscience. The kind of person who is a secular humanist today would likely have been both racialist and eugenicist 100 years ago. Ideology matters.)
Anybody who can read can see that I didn't absolve Nazism, but it looks like you're trying hard to absolve the Nazis! They can't help that they were not able to resist Hitler's ideology.
Again, don't be silly. People can be persuaded by an ideology or they can reject it. Their choice.
There are 2 possible positions for you to take though:
1. Nazism made society more violent
2. Nazism didn't make society more violent
If you agree with 1, you agree with me about violent millenarian ideologies causing increased societal violence.
If you agree with 2, you absolve Nazism from being a harmful ideology that causes increased societal violence.
Which is it to be?
