Admit it, you can't tolerate those weird aliens! They are completely different from us. They can eat the corpses of your parents today and use you as food tomorrow. We cannot coexist, we can only return to the tradition of our ancestors - war! War! War!
My compatriots, initiate the war protocol! We will fight everywhere in the galaxy, fighting for the future of mankind, even if we burn the stars and destroy the sea of stars.
