Inconvenient questions, inconvenient perspectives, arguments which can not be answered; . . . apparently there is more than one way to win a debate. Simply avoid having to have it at all. In October, someone (facebook does not share who) reported these questions and comments as violating Community Standards. So they were removed from the conversation altogether, allowing abusive name calling to go unanswered. After all, you can't lose an argument which never took place.
