In some ways, I am not sure it is worth responding because you are so angry and you seem very stuck in your point of view. On the other hand I hear your pain and your concern for the pain of others.this is a horrible thing which has happened however even though Muslims in Iran are persecuting Bahais I still cannot morally bring myself to rejoice at senseless violence and the taking of innocent lives.
I don't like generalizations because they miss the individual perspective. I have seen many people who have been wrongfully diagnosed and I do have concern for people who have been given rather toxic medications which could be a life-saver for some but are a noose around the neck for others. I wonder if some have their first true 'psychiatric episode' in withdrawal from such medications - not unlike the person who has an epileptic seizure in withdrawal from neuroleptics - most people would - it's an expected experience in quick withdrawal.
I have seen people who have found Lithium to be very toxic - others who have had no side-effects and would tell you it saved their life.I understand there is no bipolar illness in the lands where it is naturally in the water system.
Not all psychiatrists are the same either. Some are true despots whose main thrust with clients is: It's my way (take the medication and do as I say) or the highway (I won't see you if you don't just follow my recommendations). There are many others who work closely with the person discussing diagnostic issues and offering education about alternative ways of dealing with their symptoms. Many will encourage a variety of psychological therapies to minimize the use of medications or even replace medications, making managing symptoms more successful.
It would be interesting to know more about where your hurt and anger is coming from, re your experience
