Please stop using HN for political and ideological battle. It's not what this site is for, and it destroys what it is for.
How could I have answered their question in a way that does not destroy HN?
With this particular comment: it's taking the thread into a generic ideological tangent, away from the topic, on a classic flamewar theme. Also, "the US supporting gangsters" is flamebait. Please avoid denunciatory rhetoric on HN generally. It kills curious conversation, which is the purpose of this site. And it usually triggers people on the other side of the issue into doing worse.
Also, although you used the words "lots of evidence", the comment is shallow and uninformative.
Also, the link you linked to doesn't support what you said, so calling it "relevant historical documentation" is misleading.
