signal-3
Explanation
This comic imagines a first-contact scenario where aliens arrive at Earth and explain why they took so long. The aliens say that the moment Earth's signals became detectable, the content was so awful -- full of conspiracies, personal attacks, and people hurting themselves for entertainment -- that the aliens signaled back with plans to destroy humanity. However, the aliens then ask the humans to start broadcasting more positive content like "the wonder of the universe." The human responds: "Please specify your home coordinates."
The humor comes from the dark ironic reversal. The aliens initially wanted to destroy us because our broadcasts were terrible, but when they ask us to be better, the human's first instinct is to ask for targeting coordinates -- presumably to attack the aliens first. This confirms the aliens' worst fears about humanity. The comic satirizes both the low quality of human media and entertainment (reality TV, internet toxicity, conspiracy theories) and the fundamentally aggressive nature of humanity. Even when given a second chance by a benevolent alien civilization, the human immediately defaults to a militaristic response, proving the aliens were right all along.
