Again, it's a long answer, but I'll shorten it as much as I can, here.
The academy, in particular, now speaks of the activist journalist as an element of information provision. As long as you declare conflicts and let the audience know where you're coming from on a particular issue, you can, in fact, have a more activist role in society than the traditional journalist might have had. It's not my favourite ilk of the business, but I recognize it exists.
