Who argued that the notion of mental illness was invented by society (and the mental health establishment) to stigmatize and subjugate people whose behavior violates accepted social and legal norms?
a. isla fischer
b. john waller
c. marcia cross
d. thomas szasz?

The answer is d. Thomas Szasz.

Explanation:

Thomas Szasz was a Hungarian-American psychoanalist. He stated that mental illnesses should not be treated as phyisical ones; instead, they are a reflection of human problems. He argued there was no biological proof to reveal the presence of a mental disorder.

Although he's been referred to as an advocator of antypsychiatry, he denied this and would rather call himself as being "anti-coercive psychiatry".
