Not just Earth. A cameo by Hitler got our whole galactic sector cancelled. Even the hiveminds won't try to assimilate species in the region anymore because they don't want to risk guilt-by-association.
It's not even a contradiction really. The only thing the lack of aliens in the detectable universe contradicts is the false hypothesis that everything can be found in several separate locations or groups, and nothing is limited to one place or area. On this planet we have multiple cases of something existing in one place, and no where else. For example, we have lemurs in no where but Madagascar. We have kangaroos no where other than Australia. We have penguins in frozen Antarctica, but when you get to the equally frozen arctic, there's no penguins. The simple answer to why that is is that the very conditions that allowed these creatures to evolve and continue to live where they are did not repeat in other parts of the world.
Back to the original point, the lack of known aliens only contradicts the idea that whatever exists should exist in several separate places, and would never be limited to one place, which we know is false.
Well a paradox isn't the same thing as a logical contradiction. The "fermi paradox" is just a paradox in the sense that reality doesn't match up to the physical evidence suggested by some scientists. In which case it behooves those scientists to review the physical evidence and adjust their theories.
