Note: The question I was referring to below has been deleted after I made this post, and its OP's account was also deleted, but my post should still stand in case similar questions are posted in the future.
I reviewed this question in the Close votes review queue — Major Mandela effect in "King Ralph" (1991). Someone initiated a close vote that it is an off-topic identification question. When I reviewed it, I thought the core of the question, and the OP's intent, was to look for alternate versions of the film. So I edited the question in the review queue (also acting as a "Leave open" vote) to ask whether there are any alternate versions (see revision history).
However, OP has reverted my edit (and also all other edits by other users at the time of writing). When I asked OP to clarify their intent, OP responded but did not clarify, claiming that their question was "perfectly clear" (it wasn't and still isn't), that I was "100% wrong," and that I "had no business editing [OP's] question in the first place." This indicates to me that OP's actual intent is to determine/identify whether their "Mandela effect" memory of the scene is correct or if the scene existed.
I don't believe it's acceptable or on-topic to allow identifying movie scenes, that may or may not have existed, from memory on this site. (Just like identifying movies and TV shows from memory is off-topic here.) The initial close voter was correct — the question is an identification question, and I should not have voted to leave the question open in the review queue. Memory is a fickle and unreliable thing, which is one of the reasons why neither this site nor Arqade allow identifying works from memory.
Example question based on the above-mentioned question (I just changed the movie and the "Mandela effect" memory of the scene):
I'm having a major Mandela effect with "Toy Story." I saw it on the internet recently, and a scene that I remembered seeing when I saw it in theaters in 1995 wasn't there. Does anyone else remember a scene in the movie where Woody shouts "What are you doing in my swamp‽" to Buzz? It wasn't in the internet version that I saw yesterday. Does anyone else remember seeing this scene in theaters?
Is the above example question on-topic? Is it on-topic to ask "Mandela effect" questions, in which the OP asks if their memory of a movie scene is correct or if the scene actually existed?
