this has been discussed many times... do a search and you will find many opinions...
however, i disagree with you being so loose with your definition of malignant. Ortho is hard work. Can't get around it. Some use this as a definition (although i am not assuming this is yours). If you are being treated like a subhuman piece of s*&!... well that is different.
I can tell you some places that are not "malignant": Brown, NYU, CWRU, Penn, UVM, Stony Brook to name a few. I agree that i didn't come across any programs that i felt i would be abused... i just liked some over others.
my 2 cents...
