No matter how lighthearted, innocuous or mild the topic of a thread they will always find a reason to snipe, bitch, sneer or belittle. I'm seeing it more and more on AIBU - good humoured or jokey threads killed stone dead by posters who can't wait to jump on and drag it down some miserable cup de sac, cutting off any chance of a bit of fun or friendly empathising with one of life's minor but recognisable dilemmas.
AIBU to find this really annoying and irritating?
