A B.S. in physics means that you know a little bit about all of physics but nothing very well.
A wise man doesn't stop learning once he stops attending classes. You shouldn't make assumptions about strangers, they give away your ideals.
No a wise man doesn't (and since I am working on my graduate degree now that 'ideal' you hint at me having has not yet taken root). However most people do. And trusting in something with a complicated name that YOU don't understand because someone says they got a B.S. in physics is a sure way to get burned (as proven today). Especially when a physics degree does not directly prepare you for that complicated thing.
Good points.
However, if you admit you don't understand what he is talking about, so you don't really have much to add besides reminding people not to take internet forums as gospel.
