Yeah. It's a mental disease like Female Hysteria and Drapetomania....
What is the line between mental abnormality and mental disease?
What is the line between decent and disgusting? Liberals keep moving it so I'd love to get you on record.
By the way, drapetomania was made up randomly to justify acts. The designation of trannies as mentally ill has (had) been the standard for a long time. If anyone is trying to make up science, it's the left in saying this behavior is normal.
