For the love of God, do not touch our women. Duke is still pissed about last time
In reality, I'd probably say this, "Humanity is horrible. We're all greedy, self-righteous bastards who would sooner kill someone than change our beliefs. We're sociopathic to anyone outside of our circle of friends, which we call our Monkeysphere. We worship false idols and kill each other over it, oppress those who cannot fight back, and rape our planet for it's resources. We let our emotions drive us rather than logic...and those flaws are what make us great. It is through that hatred and seething emotional turmoil that great people rise from adversity to change the face of our existence. Without it, we'd be emotionless robots with nothing greater to strive for, and so we'd stagnate and turn into a puddle of grey genetic sludge. So, please, be careful for the germs, and welcome to Earth. We're glad to finally meet you"
