I don't dismiss the profession. I dismiss the professionals. They need to provide more proof then identifying as a professional exactly because it is not a science. I also need to understand their biases and agenda.
Honestly it's usually easier to just ignore them and give their opinion no weight greater then anyone else.
I agree with everything you wrote except that last sentence, and that is exactly what I refer to as "dismissing the profession". Understanding their biases and agenda is by no means trivial, or even easy, but it's most likely a lot easier than spending all the time they spent on studying the subject matter.
