So what you're saying is that we may well be the undesirable hillbillies of the Galaxy..
Well, there could be any number of descriptions of humanity:
"Ugly giant bags of mostly water"
"A dangerous, savage child race"
"You seem to find no tranquillity in anything. You struggle against the inevitable. You thrive on conflict. You are selfish, yet you value loyalty. You are rash, quick to judge, slow to change. It's amazing you've survived. Be that as it may, as species, we have no common ground. You are too aggressive. Too hostile. Too militant."
"Humans have a way of showing up when you least expect them"
"Anatomically, you humans are somewhat simplistic, but what you lack biologically you make up for with your charming optimism, not to mention your egg drop soup."
"The smell must be intolerable."
"Let me tell you something about humans, nephew. They're a wonderful, friendly people as long as their bellies are full and their holosuites are working. But take away their creature comforts, deprive them of food, sleep, sonic showers, put their lives in jeopardy over an extended period of time, and those same friendly, intelligent, wonderful people will become as nasty and as violent as the most bloodthirsty Klingon."
"We suspected that an agreement with humans would prove impossible to maintain. You are erratic, conflicted, disorganised. Every decision is debated, every action questioned. Every individual entitled to their own small opinion. You lack harmony, cohesion, greatness. It will be your undoing."
