So let's get this straight then...Because your protest should also not disrupt my peaceful enjoyment.
Many thousands of people wanted to attend and cheer the coronation, which should not be disrupted by placard waiving protesters intent on spoiling their view and being heard. Just as those who want to 'boo' military parades on "religious" grounds should also not be permitted if it spoils other people's enjoyment.
Its a small crowded country, we have to try to get along.
According to you no protest should have any effect whatsoever on anyone else?
And while you're about it, define 'enjoyment'...
Would you have objected to Emily Davison spoiling the 'enjoyment' of people watching an abusive 'sport' by throwing herself in front of the king's horse in order to get the vote for women?
