The post to which you refer was by @PencilsInSpace at 10pm last night.
It read,
I agree the lack of a sense of humour from the patronising scolds is very sad and I don't think it can be good for their mental health.
It's possible to think that and also not think that slavery is funny. And also to think that the misrepresentation of that post is quite shocking and revealing.
I read that as saying, some posters on this thread have come over as entirely lacking in humour. There is space for quips about NT tearooms, for example. It's possible to make tangential comments about the illegibility of some signage in a humorous way. Whatever. Can be done. Similar is done on many, many serious threads on this site, including by erudite posters.
And it is also possible to think that some posters have shown zero sense of humour AND to think that slavery isn't funny. You're not being asked to joke about slavery, FFS. It's just been observed that your whole tone is weighty, scolding, austere and puritanical.
I'm still wondering what counts as 'well educated' according to you, since you were so willing to sling out a lack of education as an explanation for people on this thread disagreeing with you.
