I normally check to see who this individual is and what qualifies him or her to talk about the subject in question. They usually show the name at the bottom of the screen and then the occupation as: writer, commentator, author, reporter, ex advisor to ..., blogger, podcaster, and so on.
Wait a minute. I am all of these. I am a writer. I learnt to write at the age of five. It was the alphabets at first then I put letters together to make words like: DOG, CAT, IDIOTS ...
I'm also a commentator. I have an opinion on any subject you care to mention whether I know anything about it or not; and my views are just as relevant as the next man's or woman's. Why don't they have me on TV to comment on just about anything?
I am not a podcaster because I don't know what it means. But I'm sure I can comment about it if asked.
I've even been an ex advisor to my dog until he learnt to ignore me. So I can advise anyone if they need it.
I don't mind when the subject they are discussing is of a medical, or technical nature and they have a doctor or scientist there, or an economist to explain rising prices and the GDP of a country, or some other expert on the subject under discussion.
But when they have an "author" or "commentator" or "reporter" then I would say that their views are just as valid as yours, or mine, or my dog's even.
So if there are any TV producers out there reading this I am:
