That post kind of implied that only lawyers should be allowed to comment on legal topics. People have various levels of knowledge on different things, but if someone is talking out of their a$$, they will get exposed soon enough. I don't know how many actual lawyers are on this board, but there are several of us who work in legal or quasi-legal fields and can speak intelligently about this stuff.
It's kind of like asking, if we are debating the morality of something, if you are a philosopher or a clergyman.
Ric Flair used to pretend that he taught law or some such nonsense, but it was obvious from his posting that he held no such intellectual ground, so if someone on this board tells us they are a lawyer, I would take it with a grain of salt anyway.
