A phrase mocking people that claim humans are inherently evil with no actual argument or evidence, stated in reply to the claim in bad syntax to make the OP seem dumb. the person being mocked is usually an edgelord seeking validation through self-loathing and is basing their view of humanity on social media, ignoring how diverse humans are in real life. sometimes this is also done to boost their personal agenda and get angry that others' opinions don't perfectly align with it. The claims by the OP can often be found in comment sections of youtube videos discussing the Fermi paradox or about odd human behaviors.
comment: Aliens will never visit us because we're all stupid.
