There's no particular reason why it should have been front page material -- just the time of day it was submitted and the provocative title helped, I guess. I found it interesting and am a longform journalism fan. I thought others on HN might find it interesting so I submitted it. I have no particular political agenda [1] and don't necessarily agree with all the content of this piece, but it made me think about a challenging subject and seemed like it could launch an interesting discussion.
Sorry it's not your cup of tea, just trying to add some variety to the HN submissions.
[1] The only other longform piece I've submitted -- A Death at Tough Mudder -- is about the circumstances surrounding a participant's death at a spartan race. I don't read longform to pat myself on the back when I find articles I agree with. I read it to take a break from all things tech related and to learn about new things.
