Best-selling author and feminist writer Jessica Valenti has quit using social media indefinitely, after she received a rape threat aimed at her child. Valenti has long received violent threats online as a result of her feminist writing. But on Wednesday she tweeted, “This morning I woke up to a rape and death threat directed at my 5 year old daughter. That this is part of my work life is unacceptable.” In another tweet, she added, “I can’t live like this.”
