What is the psychology of some people who are waging war against mental health professionals and NAMI?

is there any truth in their allegations that psychiatric drugs and psychiatry are being abused by mental health professionals in the usa?

There are and always will be abuse of anything and everything. It is the nature of some human beings to overstep boundaries and to apply procedures without properly affixing the problem.
I think medication can help some people, but sometimes there is over prescription of medication. It is an unfortunate fact that in the United States policies are not changed by reasonable arguments, because people cannot evaluate the value of varying positions. Policies are decided by taking extreme stands and then arguing over points in an adversarial manner. I don't know if it is because most policies are decided by lawyers and legalities or what.
The American health care system has been evolving into having decisions made by insurance companies and government. Health care is becoming less and less the realm of doctors and "practicing" nurses. It is more in the realm of health management and treating people as bodies in for repair. Pills are the oil for the system. I am particularly discouraged by mental health care in this country. It is a "take this pill, get over it, and call me next month." It reminds me of George C. Scott in the movie "The Hospital": "We heal no one, we cure no one!" If you get better, pray to God and thank your lucky stars! The next time there may be no money to help you! You've used up your benefits!
