I think I did, too. I'm sure the mods probably get all manner of complaints about offensive things - from just disagreements to actually offensive posts - and since social groups tend to have more leeway as far as controversial topics, I can imagine their inboxes have been full. Hence the sticky.
If I recall, the note cautioned to not read social groups where the topic would be irritating to you... I don't really have interest in reading social groups I don't belong to. I mean, if I had interest in the group's main purpose, I'd probably belong to it, right? But they fly by my radar just like the LCHF meal threads (I don't eat low carb/high fat), and the horse threads (1 dog, 2 guinea pigs), etc. There's no annoyance or offense for me there, either. Know what I mean?
