There is one thing I don't understand about the whole safe-space debate: People demand the environments they reside in to be friendly and comfortable according to their definition. In a way they are demanding that all "hostiles" stop being "hostile" towards them. The more sustainable way to not get hurt is to learn how to emotionally defend yourself and stand your ground. You just have to learn it once and are not dependent on others telling every attacker to stop attacking you for the rest of your life.
