I would generally find all of the above somewhat too pedestrian as topics, if they come up too often. Also, I've discussed all of the above at work with coworkers recently, and when things do veer into the political, they don't go too deep (though at my current job, we're free to be quite acerbic) and the conversation veers away to something else. I guess we treat the avoiding taboo topics more like not driving on the lines, and less like driving over a minefield. We generally avoid for safety's sake, and don't expect things to blow up immediately if there is a bit of driving over the line. (Hell, we even talk about guns and gun control!)
