keep in mind the focus of this board. It's about early retirement. It's not about full contact politics; there are plenty of other places to go if you simply want to argue politics. In fact, i think your comment is evidence as to *why* generic political discussion needs the kibosh. It's because many people who enjoy full-contact politics are incapable of keeping it civil ("polite" and "subtle" to use your words) that we felt this is necessary.
You say we "can't be polite... With people who are wrong." two problems here: First. You can be polite with people who are "wrong"; it is possible to disagree with someone without thinking they are evil or stupid. And if you can't, that's a clear violation of the terms of service and the community rules. That's one of the things that personally depresses me about political discussion; sometimes it seems like people can't accept that intelligent and well-meaning people can possibly be "on the other side."
the second problem is that there isn't usually a "right" and a "wrong." there are merely two different perspectives. Okay, in extreme cases there may be right and wrong, but that's not the norm.
I hate to say it in some sense, but in my opinion what you said is exactly *why* we need to get rid of the soap box as we know it. Too much allowance on politics tends to create an us-versus-them attitude that can harm the sense of community and common goal that should bring us together. This forum is about early retirement. When political issues relate to fire, respectful and on-topic discussion of the political aspects is acceptable. When it bursts into flames, and when it has nothing to do with fire, it just divides us and makes life miserable. Who wants that?
