Totally agree on Gabor Mate. He is a giant visionary. I don't know of any other mental health professional with his level of insight on human conditions. What I appreciate about him the most is that he doesn't separate social and economic problems from mental problems of individuals but points out that our individual mental suffering is to a large degree caused by socio-economic conditions. He challenges the mental health profession to acknowledge this reality and to be on the frontier of social, economic and political reforms and argues that it's disingenuous to make individuals carry the load of the collective problems of the society. I completely share this view. In fact, this is the view that was introduced into the mental health profession back in 60-s and 70-s by postmodern psychotherapy that emphasized the ideas of feminist movement in therapy and tried to challenge and deconstruct the existing cultural narratives that were and still are influencing the profession. Unfortunately, their ideas didn't get big traction and were soon dismissed by most mainstream practitioners.

As to Terry Lynch, he is an Irish psychiatrist, also a deep thinker but not exactly of the same caliber as Gabor Mater. He is a mental health activist who is committed to challenging the profession and has been doing it for many years already. One if his books "Beyond Prozac" was published back in 80-s and was quite popular. Here is one of his video talks that may give you an idea of what he is doing Therapy Consumer Guide | Misinformation in Mental Health If you want more information just google his name.
