reason number 8789 why I don't like the Sherlock Holmes fandom

I'm so glad I never gave a shit about joining that Letters from Watson thing as even without participating in it this is the second time I've seen someone post something about it that's just incorrect and actually has canonical evidence to prove they're wrong, someone else in a friendly and not condescending way comment about this and the original person just fly off the handle about it for no reason at all, start being all snide and condescending in return and throw a massive tantrum over it. They start screaming about "Holmes know it alls jumping on them" and blathering on about things the other people never said or did at all and with the other one too it was them raging about "spoilers!" and how this person is 'ruining everything for all the Letters from Watson participants' when, uh, 1 what the person said wasn't even a spoiler, 2 it's a like 100 year old story are we really still going to be pulling the 'spoilers!' card after a fucking century, really?, 3, it was a reply on a post that barely anyone would see and 4 that story they referred to is not even being included in Letters from Watson anyway. 

Me watching from the sidelines: are you OK
