It might have been too pedantic, perhaps.

I don't quite get the sarcastic and aggressive tone here, but ok. I don't think we much disagree here. I'm pointing it out for those who might not know. I do agree with you that these are the accounts that'd typically be taken as 'quotes of Socrates', as the anecdote about Socrates' wife being a tamable horse in Xenophon's Symposium is taken as though he said it.

And if you think that 'Plato is not an accurate depiction of Socrates' is known by all undergraduate philosophy students, you'd be surprised how many tenured classics professors seem to hold the opinion.

There are a few scattered anecdotal accounts of Socrates that are intended to be accurate (even if not from historians). I'm not sure if one could derive a quote from them.

And none of those would be considered quotes of Socrates, as each of those authors is presenting their own dramatic work.

The only quotes of Socrates that could be regarded as true would be from historians who are trying to make an accurate record. But Plato was trying to present a certain philosophical message himself, and to make something that is dramatic.

The method of dialectic is not very conducive to writing, as one needs to be able to ask and answer, but a reader can only read and can't be questioned directly.

It's OK. Most 'actual' quotes from Socrates are not from Socrates either, but from the character Socrates in a book by Plato.

The costume is thought of as the performance now, I think. Some refuse to give candy to those who are too old or not dressed up
