TBH that doesn’t surprise me… I had a minor spat over the existence of a local supermarket, of all the stupid things… Wiki said it had been refused planning permission and never built. I had shopped in there many times, and could link to many articles about the fully built existing supermarket. I gave up after the second revert because it’s just not worth it.
Happens with americans too… they seem to completely miss sarcasm sometimes. Humour is very cultural (and often plays into things a native of the country would know but someone outside sometimes wouldn’t).
