Explain the significance of fear as an emotion for survival, and how it is relevant to the case of Trump.
Fear is an emotion meant to ensure survival, as much as pain is a sensation meant to alert the body to damage so that it can be addressed and fixed, again to ensure survival. In Trumps case, it's sensible to fear. If you don't, you're stupid. So enjoy feeling fearlessness.  It won't be long before you feel pain that you cannot ignore or fix with a snide comment.
