Twitter censors user for saying transgenderism is a mental illness: A Twitter user shared a screenshot of his censorship notice. He tweeted: "Digging in on the immutable fact that biology determines what you are, not your feelings. Your chromosomes determine what you are, except in .028% of humanity (thank you @scrowder). Transgenderism is a mental illness tat requires grooming to grow the population." Twitter found this violated its policy against "hateful conduct."
