A Spanish MP was suspended by Twitter for 12 hours after he responded to a news article and noted that men do not have the biological ability to become pregnant.

Francisco José Contreras, an MP for the populist right-wing party Vox, posted a news article to Twitter about a Spanish female-to-male transgender individual who was pregnant and recently gave birth to a daughter, with the article in question claiming that this made this individual a father. Contreras in his tweet said that this was a total lie. “A man cannot get pregnant,” he tweeted. “A man does not have a uterus or ovaries.”

However, not long after he tweeted his statement, Contrera received an email from Twitter, claiming that he had violated their rules on “hate speech,” informing him that they do not allow material that “threatens, harasses or promotes violence” against anybody based on a number of personal characteristics, including gender identity, among others. The email also warned him that repeated “breaches” could lead to permanent suspension of his account.

Contrera posted the text of the email on his Facebook page, where he revealed that he had been also forced to delete the offending tweet. The Spanish MP described the incident as being “biological fascism,” and joked that next time he would get suspended for saying that 2+2+4. Mario Noya, a journalist, and convert from being a left-winger, tweeted his support of Contrera. “Twitter SUCKS,” Noya said.
