Your immune system really woke up and chose violence against peanuts while treating actual pathogens like casual acquaintances. The swole doge represents the absolute overkill response to harmless proteins—anaphylactic shock, hives, throat closing up—meanwhile the weak doge is your immune system barely mustering a cough when influenza shows up to wreck your entire respiratory system. Allergies are basically your immune system being that one friend who's chill about actual problems but loses their mind over the smallest inconvenience. A peanut protein? DEFCON 1. A virus actively hijacking your cells to replicate itself? "Eh, we'll get to it eventually." The irony is that allergic reactions involve IgE antibodies going absolutely nuclear with histamine release, while many viral infections get a more measured (sometimes too measured) response from T-cells and other immune components. Fun fact: The hygiene hypothesis suggests our immune systems are bored from lack of parasites and bacteria, so they've started picking fights with innocent food proteins instead. Evolutionary biology didn't prepare us for living in sanitized environments, so now we're allergic to shellfish.
