I do believe the TSA stories represent a danger. If there's a road from hacking to politics, it's probably civil liberties. So already for the past week TSA stories have had an automatic penalty applied. Or more precisly, they've been autotagged as being political, which entails a penalty.
There are no TSA stories on the frontpage at this moment. In fact, the frontpage is a pretty normal HN frontpage now.
This comment thread is a perfect example of fanboy pile-on voting against a well-reasoned but unpopular point of view : http://news.ycombinator.com/item?id=1888239.
Don't you think turning off HN (literally) for a few hours every now and then will help? Sure, it won't be convenient and some people will complain but it's still worth a shot. It will at least improve the world's productivity by a few % points. The next Google might be born.
