Man, you are one confused individual.
"Reporting" can be on anything, not just news as your argument currently stands. He is reporting on a topic that interests him and potentially his viewers. After that, he provides his opinion on it.
This is what is referred to in English 101 as an "Opinion Paper." You pick a topic, explain it, then issue your opinion. This is what Bill O'Reilly does. He picks a topic, explains the topic as it makes sense to him, then opines.
