I don't know anything about Thompson as a person, so I'll refrain from judging. I'm only glad that I'm finally able to put a term to what I despise most about journalism in our country (U.S.), evidently the term is "Gonzo journalism."
"Gonzo journalism tends to favor style over accuracy and often uses personal experiences and emotions to provide context for the topic or event being covered." --Wikipedia
I don't care about what the journalist thinks or feels. I'm an adult and I can form my own opinion, based on my values. Give me the facts! Just please give me the damn facts, I beg you! I don't need the anchor to "show attitude" and give me "what if" scenarios to wiggle my imagination while bending the facts in the process.
Currently, this technique is king among the major news networks in the U.S. It makes them completely incapable of reporting the news in its natural form: facts. It is unethical and amoral for journalists to swing public opinion with eloquent narrative that favors "style over accuracy."
