Last week, Chicago Public Radio show, This American Life, discussed the American Psychiatric Association’s long time classification of homosexuality as a mental illness. The show covers the arguments made in favor of the categorization, the activists that protested it, and finally the movement from within the institution that managed to remove homosexuality as a mental illness in 1973.
