ECONOTIMES - July 23 - Mark Zuckerberg recently announced plans to ban a "wider category of hateful content in ads." Twitter, YouTube and Reddit have also taken additional steps to curtail online hate, removing several inflammatory accounts. But they all overlook a gun talk. The word "gun" appears but once in Facebook's policy on "Violence and incitement" to bar the manipulation of images to include a gun to the head. And neither "guns" nor "firearms" are mentioned in Twitter's policy on "Glorifications of violence," or YouTube's guidelines on "Violent or graphic content" or within any of these networks' rules on hate speech. Gun references have become prevalent in social media dialogues involving the nationwide protests over racial injustice, police reform and the BLM movement.
