Until 1973, was included in the dsm as a mental illness.

The right answer is homosexuality. Previously homosexuality was considered as a mental disorder, however, the antecedents to indicate the diagnosis had a more cultural and religious basis than scientific. This is why the diagnosis was reevaluated considering that if the individual feels comfortable with their sexual orientation and this does not interfere with their personal, social or work development, then not a disorder.

I hope my answer can help you.
