Retconning and removal

I'm of two minds about FIMFiction allowing you to edit chapters after they've been published. On one hand, it helps a ton with grammar or stylistic mistakes you might have missed in pre-publishing. I'd be lying if I said I didn't occasionally need it.

On the other point, it feels kind of dishonest to edit out inconvenient plot points.
Look, I hate retconning. If you're not familiar, it stands for "retroactive continuity," and what it boils down to is explaining away inconvenient events in a narrative after the fact. The iconic example is that of the "death" of Sherlock Holmes.

Arthur Conan Doyle was getting sick of the character, so he had him and his nemesis plunge to their deaths, thus ending the Sherlock Holmes series. The readers didn't take it well. In fact, some of the first recognizable fanfiction was written in response to it, explaining that Sherlock Holmes had somehow survived the fall. In the meantime, Doyle's new series didn't achieve anywhere near the popularity of the Holmes novels. So he was forced to have the detective magically survive. That's a retcon.

I don't like that. It's almost inevitably contrived and obtrusive.

But then there's the temptation to go the opposite end, which FIMFiction allows you to do quite easily. You can just remove the inconvenient line that could trip you up later, and it disappears without a burp. I'm not going to point out where I've just done this, but I'm kind of terrified of an observant reader finding me out. It feels dishonest.
