1) I can guarantee you oil extraction from places like Nigeria isn't free of child exploitation, but I bet you continue to make the lifestyle choice of driving.
2) I didn't say adoption is bad for smart parents I said its not equivalent to having children of your own for smart parents. There aren't exactly a ton of children of high IQ couples in the adoption market. My bother in law is adopted and he is a doll and adoption is great. But it's not completely equivalent to having your own kids.
1) That is very obviously and intentionally not a response to what I asked. I barely, barely drive as it is. I commute to work, I'm within biking distance of my grocery store. Besides, transportation is sort of essential in the United States to commute and buy food. A diamond has none of that utility. None at all. The fact that you compare them, use it to justify any sort of exploitation is incredible.
2) I should've let it go, I have no desire to argue to have an irrelevant discussion about adoption that already offends my sensibilities.
I'm not really trying to single "you" out, FWIW. I'm using a generic "you" at a website full of people who likely choose to drive around in the suburban wasteland that is Silicon Valley, who likely work in an industry that repopularized the sprawling suburban office park, and the hypocrisy of their complaining about how other peoples' lifestyle choices are hurting people in Africa.
He's pointing out that you have a relatively weak argument to be standing on if you are going to get outraged over how evil diamond are, then continue to happily consume dozens of other "evil" products in your everyday life. The only reason these other "evil" products are being brushed under the table is they are much harder for you to do without day to day than a diamond.
