I don't think it's sad, politics are supposed to change. Obviously you can be sad at specific changes, but the idea that political decisions in general can change is a good thing.
So we went from a time when tracking or reading your communications (mail) was unconstitutional to the present, where the government can track you, listen in on you, and record all of your (electronic) communications 'just in case' they might want to check what you've been doing. Doesn't leave me inspired with optimism.
I'm only responding to "Political decisions simply don't stand. It's terribly sad." I'm sure we can all think of many examples of good political changes. In fact, I think most people would agree that good political changes vastly outnumber bad ones. Blaming current problems on the entire nature of politics seems a little overly broad. We would not be better off if we froze all politics forever in whatever your favorite year was.
