Because it's a traditional flame-bait subject and will never produce useful discussion. Sure, some of the things you mention would be interesting, but this article does not discuss those, and even if it did discuss those the comments would still have very dull repetitive flame-baiting; and they would be the same comments seen for many many years.

No, it's just a really un-interesting topic for HN. As other people have mentioned there are much better places for this article. 4chan, or reddit, for example.
Coincident: A leading human rights figure got a lot of flak for writing a newspaper article saying that our (kenya's) next president will not be from the same ethnicity as the current. Not a wrong fact just a speculative opinion but because people are touchy when it comes to talking(in public only) about ethnicity since the last bloody elections, people were calling that an incitement and (this is now a media buzzword) 'hate speech'. Question is: can we hn-ly discuss a related topic without getting into the touchy and flamey parts? Far shot but if someone noticed something hn-worthy(like a data pattern or a behaviour pattern) in something as off-HN as say lolcats, will it be impossible to talk about it?
And now I have just been banned for this comment despite 4 upvotes...
And I can see that user "babbling" has been banned for this comment :
"Except that the Israeli Palestinian conflict is interesting to a lot of people and Hacker News tends to have more civilized discussions than some other places"
This doesn't feel right.
But I'm here questioning the value of the discussion. If the Kenyan gov. removed the solar plants then there should be some reason, and that's worth discussing. I don't think that any (sane) gov. would remove solar plants providing free energy?
The value/(probability to start a war) of the article is close to 0. That's why I flagged the article. It's still my opinion, and I gave my argument. Certainly, I'd respect the HN community choice of what to discuss and how to discuss it.
So now ask yourselves, why is it different all of the sudden if we put "Palestine" and "Israel" back in the article.
Could it be that some here have an irrational and knee-jerk responses to that particular region of the world? If so, maybe that is an interesting discussion. How come a group that fancies itself more rational and straight thinking than others, has such strong biases one way or the other? Why is there so much discussion about this topic.
Are people driving an article down and flagging it as "inappropriate politically" not because they are trying to keep HN pure but because their own disguised biases are telling them to act that way.
