Something I find frustrating is the - almost - endless debate and nitpicking on small details or elements implied but not explicitly stated...but I guess people are trying to be helpful (or right).
I didn't have an account to comment then but I really appreciated your perspective; it was extremely valuable seeing a few people saying 'forget about the credit/debit nomenclature, it's confusing' and recognising not everyone knows the terminology. Now I have an account here and can thank you for fighting the good fight again.
Over the ~20 years since I qualified as an accountant, I've found the concept of debits and credits useful. It has saved me from memorizing rules (like what's on the left and what's on the right), to design charts of accounts, to design rules for recording transactions etc.
Someone who doesn't ever need to design charts of accounts or accounting policies, and is never called upon to verify the correctness of an accounting approach, probably doesn't need to understand debits and credits. They can read a balance sheet and income statement without thinking about the concept.
And many people (even bookkeepers and accountants) are content to memorize rules without needing to understand their source.
But that doesn't mean the underlying concepts don't exist, or that they aren't valuable.
Imagine if there were a subreddit for accountants, some of whom dabbled in coding. There might be a back and forth about principles of objects oriented design. The general consensus might be that it's pointless to understand the principles, and that it would be better to focus on some small set of rules of thumb, that give the right answer in most cases.
They might be right in that context (accountants who code on the side), but it doesn't mean the principles don't exist or aren't valuable for people who do that stuff all the time.
(BTW I think accounting is, in general, taught very poorly. I wish more instructors used Frank Wood's books. An intuitive grasp of debits and credits is really useful and not hard to pick up, yet many people spend a semester studying accounting without developing any intuition at all.)
