You were disappointed that there was a moderation warning when some people are celebrating her death? Her job was to take pictures and open hospitals. And random people who dislike the idea of royality or dislike the UK are posting some rancid patter.
Sure all, it's all over the top, sure many people don't care. The warning wasn't there for people who didn't care. It was there because there are literally people going around acting like this woman was a war criminal when she held no real power, if she ever tried to use any power she technically had it would have caused chaos and resulted in that power being removed and the royal family being removed. Some people acting like Indians would be dancing on her grave even though they've been indpendent for all of her reign and every Indian I've met has been interested in the Queen and royal family like all other people are. Or the Irish are happy she is dead, maybe in the 80s or 90s at the peak of the troubles but most people won't care just like most people in the UK don't care.
And let's be serious, you won't have to bite your tongue that much since most other people will be complaining about it all in a few days.
