Lots of journalists say lots of stupid things and offer opinions on things that they know little about. Think of them as regular forumites on a field trip.
Today, social media allows everyone to be a reporter and show things from their own perspective. In that regard, an F1 journalist is much more like one of us if they have otherwise been insulated from social and political upheaval like this. I find their naivete and surprise at the situation quite refreshing.
I suspect that what looks like muddy waters to you is just an inconvenient reflection of the wider conditions within the country which make you think twice about the effect your benign viewership and support for the sport might have on others. One might equally feel the same if confronted by tweet-pics of the slums around Sao Paolo or child workers in India, but these are not so immediate to the F1 circus and not so interesting to us as consumers of news.
Good point! Especially regarding the forumites. I guess we'd all report something different based on our own beliefs and feelings about an issue.
