Homosexuality was a disease according to the [American] DSM, until 1973, when it was partially normalized along with LGBTQ and all of them put in another category called Ego-Dystonic Sexual Orientation. At this point, they could still be "treated" because it was still considered abnormal. This lasted until 2013 in DSM, and 2019 in WHO's International Classification of Diseases (ICD).
"It's not a bug. It's a feature."
This is a good description of normalizing what has historically been seen as a disease everywhere on the globe. That means: no more looking at how to ameliorate this obvious deviation in human behavior.
From a purely scientific, evolutionary and biological perspective, this is a death sentence, abnormal, outlier; considering that the biological sciences define the purpose of all life, from microbes to animals to trees, as the propensity to reproduce and procreate. But here we have orientations that refuse to procreate employing both physical and behavioral barriers.
By this crooked logic ("it's not a bug"), I wonder what prevents them from declassifying other mental disease as normal "features". Say, for example, a pedophile.. why not also label his mentally deviant preferences as just ... "personal features"?
