Ok. You're not into the monarchy. That's fine. But why try to ruin everyone's day?
I remember when we all had different opinions, but we stayed out of other people's affairs.
People who like horse racing went there - and the people who didn't like it went somewhere else.
These days, some people seem to have nothing else in their lives other than objecting to the way that other people are living theirs and they feel the need to try to ruin it. If you really have nothing to add, just stay home.
