People ought to be able to say why genocide is idiotic and wrong, not just think that it is.
It's called "not being raised by shitty parents and have two brain cells to rub together." It's not "fragile." And it's unevolving because it's a core value that there isn't much if any wiggle room on, it has no need to change. Unless you can articulate a situation where exterminating an entire race of people is actually a good thing. (MSH We're not in the 40k thread!)
I don't disagree people should be able to articulate the logic behind their beliefs. It's just, in this instance, there's so need unless you want to have a pre-school level conversation about why hurting people for your own gain is bad for society.
It's like, do we really need to debate why NAMBLA isn't a good thing, or can we just say that preferentially having sex with children is bad.
You start to run into inconsistencies that can make you believe crazy things if you aren't able to apply criticality. Most everyone believes that genocide and child rape are wrong, but that's also not how people who do believe crazy things frame them for others to see and is manifestly unhelpful when considering more gray issue variants.
For example, even literal Nazis will often say that "genocide is wrong", but they aren't talking about
murder, you see, they're committing an act of regrettable but necessary
self-defense which may in extremis require liquidating the Jews. Why, even Hitler only wanted to send them to their own homeland in Madagascar before imperialist invaders of German soil forced his hand. Now, I know that's crazy, and you know that's crazy, but both of us are the kind of people who go on discussion forums and lock horns all the time. We have to be critical. A lot of people are not critical, their thoughts may genuinely not extend far beyond "Nazzies = bad, genocide = bad, America = good, self-defense = good" in the same way that I don't think a lot about organic chemistry because I've never studied it. Something about carbon, I think.
And this creates a problem when an uncritical non-Nazi comes up against a critical Nazi or someone repeating the arguments of one. The Nazis are bad because they committed genocide and America is good because we defended ourselves and others, but this turns into scrambled eggs when the Nazi says that Germany was only defending itself, was basically forced to commit genocide against the corrupt establishment placed on them by the League of Nations, and that the Allies were the only ones to willingly commit genocide against German people. And arguments for genocide are almost
always predicated upon a justifying framework of "absolute necessity" or "self-defense" like that. (Funnily enough, the very same arguments used by the Imperium in 40k
)
Effective? Maybe not. But from listening to internet alt-reichers praddle on I can just about
see that they grew and watered those beliefs from this kind of quibbling. It works sometimes, but against a critical mind this sort of thing works about none of the time, which is why critical thought is so manifestly important.
That's not even the worst thing though, because that form is limited. What's the worst is how uncritical thought about "core values" warps analysis of grey areas and edge cases. Genocide is wrong, but is it wrong to wage war to protect yourself even though it means committing a functional genocide if you win? What about waging war for motives
other than protecting yourself, with the same consequences if you win? What about the way having a sole superpower affects the ability of other nations to commit war and genocide at all, is that pile of corpses worth the other one? These questions have answers that can be applied, but not by someone who just uncritically thinks "genocide is bad and self-defense is good". When the public at large thinks that way in a democratic system, we have a serious fucking problem on our hands. We have people who say "turn North Korea into a parking lot and let the Chinese sort it out" unironically, in public advocacy of
policy. And if that doesn't scare you, it should.
So yes, we need to debate why genocide isn't a good thing. It's necessary to demonstrate the process of philosophy and rhetoric to those around us who didn't learn or have not yet learned what they believe and why they believe it.
