In case you're not a first-language English speaker: the wording here implies that they're having a childish emotional reaction to what you said, which (if intentional) is an entirely inappropriate method of discourse, especially when all they did was give a very reasonable and level-headed critique of your definition of homoiconicity (that it's a property of the internal representation, not the external syntax).
