The political discussions that make their way into HN are very US-centric and that excludes me and countless others who actively participate here. A lot of such discussions are not real enough to me - they are problems of a much more privileged world. If we were to have truly political discussions, we'll need to include all the other countries of the world, which none of us would want. There are other places where political conversations are dime a dozen, but no other place like HN for technology, and things that "gratify one's intellectual curiosity".
