That seems uncharitable - the person you're replying to is saying that debit/credit are more than fundamentally abstract, and that they have conceptual meaning consistent across all accounts.

Except programmers quite often get the conceptual meaning wrong and incorrectly generalize further. Credit and debit just mean increase or decrease in account balance. You cannot know how it affects liabilities or assets without knowing what type of account is being modified.
