Genuine question, why do so many people detest the monarchy? I believe last year it cost £1.29 per person in the UK to fund the Sovereign Grant. I appreciate not everyone in the UK pays tax so call it £2.50 per year to the tax payer, so surely it can't be a financial reason to hate the monarchy. The Prince's Trust and the Duke of Edinburgh's schemes are amazing and really changes the lives of thousands of people.
I would regard myself as someone who respects the monarchy and is proud of the history. It's a big part of my identity of being British. It brings thousands of tourists of all races and religions from all over the world to visit the UK.
On the other hand, I wouldn't expect anyone to be forced to hero worship the Royal Family. There is plenty going on in the world that I find staggering but it doesn't directly effect me or my family, so I just get on with it.
So to sum it up, I reckon the UK are better off with the monarchy than without.
