I said that you'd land on the conclusion of allowing it, presumably despite your own personal preferences. Many people who opposed abolition also personally opposed slavery, but used arguments identical to yours to oppose action against slavery. The lack of action would've, obviously, allowed slavery to persist indefinitely.
Can you explain how (or if) your moral system would prevent you from landing on that conclusion? It's a simple question that doesn't depend on theatrics to ask nor answer.
My question to you is, do you believe the United Arab Emirates is more righteous than the United States? According to many measures of "goodness" like the Human Development Index (and the inequality-adjusted Human Development Index) the United Arab Emirates is a more "good" place than the United States and therefore, in your view of comparable righteousness, the United Arab Emirates is a more righteous place? Yet, the United Arab Emirates is, to many westerners (including myself and I am sure you) a place of many moral ills (including one of the most heinous: slavery). Do you believe that on your multi-dimensional most-good morality spectrum the United Arab Emirates out ranks the United States?
I'll answer that for you: no, you don't. And deep beneath this facade of objective morality, you know that morality is so deeply ingrained in your cultural upbringing that you cannot sincerely state that the United Arab Emirates is more righteous than the United States, and that regardless of what any measure, whether it's one dimension or many dimensional, whether it's black and white or a spectrum, regardless of what that measure says, nothing is above your sense of what is right and what is wrong.
Not clear what point you’re arguing against by saying “HDI says UAE is good yet you don’t agree with it!” Why on earth would I defer full moral judgment to HDI?
I never claimed my moral system is objective, so I’m also not sure what facade you’re referring to.
You may assert it but morality is not defined by or measured in outcomes, morality is a cultural product. If your moral system is not objective, if your moral system is a culturally-influenced personal belief in what is right and wrong, it is totally incoherent to say that Saudi Arabia has not made moral progress or that they have not used "modern thinking" because by their moral standards they have, and by their moral standards you (and I) are the immoral.
If you'd like to compare the United States to Saudi Arabia on human rights, press freedom, education, crime, freedom of religion, gender discrimination, do that. They have outcomes that we can measure, and don't worry, they're influenced by morality, so you can still pass judgement.
I hope I wouldn't need to say it, but for the record: I oppose slavery. I oppose gender based discrimination. I oppose sexuality based discrimination. I oppose racism. I oppose the death penalty. I oppose drug criminalisation. I oppose the American prison system. I oppose the smug western superiority complex about our behaviour being "modern" or the "best" or "ahead" of the rest of the world. I oppose referring to Saudi Arabia as "not modern" (or backwards or whatever term is in right now) which I believe is patronising and a view reserved for those without the willingness to be introspective.
For the oppressed gay man in Saudi Arabia, there's a gay man homeless on the streets of the United States, dying from neglect, after being kicked out of their home as a teenager by their Christian fundamentalist parents, thrown to the mercy of a society that couldn't care less about them. Let's put them on a spectrum, how many points is "dying homeless on the streets of America because of being gay" compared to "can't be openly gay in Saudi Arabia"? How many points for "robbed on the streets of San Francisco for the 8th time" when compared to "can leave valuables out in public without concern because there's so little crime in Singapore"?
If your vision for a better world starts with disparaging Saudi Arabia, I fear you are deeply uninspired and will not have the impact on the world that you could have if you instead focused on yourself and your culture. I also hope someday you appreciate the irony of you having worked for Palantir of all companies while talking about moral superiority of the west. I wonder where Peter Thiel would land on our Spectrum Of Moral Superiority. Actually, I don't want to know, let me live another day without reading a defence of that ghoul.
