Contreras said in a Facebook post on May 11 that he had received a message from Twitter which informed him that he had violated its policies on "hate speech" for the remarks." "The hateful tweet (which I was forced to delete) was one that said: ′′A man cannot get pregnant. A man has no womb or eggs"," Contreras wrote in response to the move. "You can see this is already fascist biology. Next time I'll try 2 + 2 = 4." According to Twitter, Contreras violated its policy against material that threatens, harasses, or fosters violence against other people on the basis of their race, ethnic origin, nationality, sexual orientation, gender, gender identity, religion, age, disability or disease.
