Yeah, I’m not a fan of that. Sadly, that’s probably the most representative stuff they do. If you look at the people who don’t do as much of that, they end up being unpopular or, ironically, more divisive. The people you’re talking about are the ones who get all the attention.
My thing is this: it’s a messy country. The government is probably going to reflect that, and you might even argue that if it didn’t somewhat reflect that, then there would be a problem with legitimacy. A lot of people either don’t know about, or don’t care about process, which is necessary for the rule of law, but which makes things messy. Some people believe that when anything happens that they don’t like, or when anything doesn’t succeed, it’s evidence of dysfunction or corruption. So another irony is that if you expect too much from politics, you’re likely to be cynical, while a more informed attitude is likely to result in expecting less of politics (or, at least, having a longer view and recognizing how hard it is to achieve your goals) and being less cynical.
