Not a cliché as such but a trend, especially in AIBU, to accuse the OP of lying. I remember my very first post here, many years ago, and it was my first ever post on the whole site. Admittedly I was user1111111 or whatever so that possibly raised an eyebrow, but I was describing my situation and which involved giving the back story of a description of (the lack of) transport options at night in rural Ireland. A number of posters came on and accused me of lying, saying it couldn’t possibly be that bad, could I not just get an Uber, there simply had to be trains available etc. The more I reiterated that there weren’t such options, the more others doubled down saying ‘something sounds off’ and ‘it doesn’t ring true’ etc. People who most likely had never set foot in rural Ireland in their lives, but nonetheless felt they knew enough about the transport logistics there to accuse me of lying. There were of course some lovely posters who stood up for me too. But I have noticed that pattern of picking holes and not believing the poster, as if they’re fucking Sherlock Holmes. I wonder do they think they get shiny badges for sniffing out a troll or something
