I've never been a monarchist and as such chose not to watch the coronation yesterday. Yes, we have freedom of speech in the UK, quite rightly too, but this is frequently used to disrespect others and that is an abuse of the right. If you don't want to sing the national anthem, then don't sing it, but booing it is not only disrespectful to the monarchy, but also abuses the respect of those that do want to sing it. Sadly there are many in the UK, who are either unwilling or unable to voice opinions in a respectful way, and seemingly don't care what impact they have on others. If this had been an occasion to mourn the loss of a person in the monarchy, would they still react in the same way, and in doing so mock someone's death?
