I attended a pagan event last year in Croydon, and there was the obligatory protest by local Christians, but strangely there was a group of American fundamentalist Christians who had come over to the UK just to demonstrate at this event. They were very unpleasant to people waiting to enter the venue (including frightening some small children) and they took video

They do have a way of sticking their nose in places where it doesn't belong.
