Twitter censors user for tweet about transgenderism: A Twitter user shared a screenshot of his censorship notice. The user tweeted "Man and woman are defined by biology. XY sex chromosomes = man. XX sex chromosomes = woman. Transgender is a mental disorder known as gender dysphoria. It should be treated by a psychiatrist, not a surgeon." Twitter claimed this violated its rules against “hateful conduct.” The user’s account was locked until he deleted the tweet.
