That's my whole point. A lot of people who are a lot more credible and who can just get down to business and cut out the theater are doing this a whole lot better than Mr. 4-doctoers here. Sorry, but I know the guy well because he inevitably shows up on all sorts of issues, is wrong on many and causes confusion.
You would never use the guy as an expert witness because the other side would delve into his known past and make mincemeat of him.
I mention my PhD here in this context only because my special expertise is digging out technical flakes and frauds because a lot of money is at stake. Otherwise I weigh the value of what people say by what they say - and whether they can get to a solid relevant point quickly backed up by evidence - with little weight given to their degree or degree of degree unless they start to make a point of these, then it suggests that they are drawing attention away from what they are saying and standing on their authority to say it.
