FWIW, I think that my old granddad was right when he told me never, never to discuss religion or politics, but to hold my own counsel and leave it alone.
Of course, the Internet didn't exist during his lifetime, but apart from that tiny detail, not a lot has changed about people, beliefs and dangers of mixing up the two deadlier sins that came post-Commandments...
I have sometimes visited the political sin-locker, but in the end, found it gave no pleasure but plenty of upset nerves, even within cyberspace.
I certainly don't think that the CC should vanish; it offers a convenient space for lots of other subjects beyond snaps, glass and camera bodies. Few of us are so limited that we don't have the ability to throw around other interests in-house, as it were. It just requires one avoid the useless ones, where we all know that there isn't a snowball's of changing hearts and minds; in effect, it's just a public wank or declaration of love for those who would always use you to their greater advantage. As someone pointed out, it's the same racket in every country, only some are more subtle about it.
