Most guilty people will immediately try to become the victim. Ignore the fact that I convince gullible people to buy junk that at best is useless and at worst will harm them. Ignore the fact that I use my medical degree to trick people. Look at the big bad corporation over here that wants to attack me. Ignore the fact that I am in the arms of a big bad corporation that airs my tv show and wants rating no matter what.
My problem with Dr. Oz is not that he appears to be a unethical charletan that will prostitute himself to any snake oil salesman who asks. My problem is, n the few shows I have seen, is that he actively is teaching his audience bad science. This is not surprising as doctors are not scientists. For instance, there was one show on fat where his depiction of fat was completely inaccurate. The demonstration was there to be visually exciting, but at the expense of any real science. I can imagine the people who saw it going to their doctor and arguing a point, thinking Dr. Oz is right, and their doctor is wrong.
It is entertainment. I agree that persons who are fundamentally entertainers and not seriously committed to medicine should probably not be the medical staff.
