I'll never forget the answer one gave me, "Look Daniel, lawyers are not like doctors. A doctor helps you fight a disease. Lawyers, on the other hand, fight other people. Every time you employ a lawyer in litigation, if he is successful, somebody else suffers. That means that there are going to be a lot of people out there who don't like lawyers"
Lawyers exist to fight. That's their job. Even if they don't have a case ("If you have the law on your side, yell about the law, if you have the facts on your side, yell about the facts. If you have neither, just yell"
I don't know if I would go making phone calls, but I would sure as hell poke back at a lawyer if he poked at me. I would like to think that folks like us with lots of ability to assimilate technical details could at least make some kind of showing -- perhaps enough to run them the ones off who are just bluffing.
