Does it matter? I prefer that you judge my posts by their content, not by my credentials -- or lack thereof. That's how I judge everyone around here. Besides, I don't like to provide personal information on the internet.
Anyone can claim credentials, but their postings often contradict such claims. And for those few whose posts are consistent with their claimed credentials, there are always those who reject their information due to anti-intellectual leanings.
All I do is post my own thinking, or I provide information (always with a source) that I believe to be reliable. Judge it on the merits. I've never claimed to have any expertise, and you should assume that I have no academic scientific credentials at all.
Nowhere else can I find such entertaining interaction involving large numbers of conservatives who are either: (a) truly educated and intelligent people; or (b) truly un-educated people with no rational capacity whatsoever. It's fascinating
Now setting aside the condescending attitude,more at home at DU than here,perhaps it would be helpful to know the qualifications you have to set yourself up as the judge of who has "rational capacity"
