If you flew the flag of St. George, here where I live, you would be lynched and your entrails would be used for the local delicacy.............Haggis 
By the way did you you know that St. George wasn't english.......... I didn't know that 
.....and St.Patrick wasnt Irish (he was a Scot),Its all a bit strange this patron saint business.In my experience the English (or more specifically English pubs) seem to celebrate St.Patricks day more than the Irish but not quite as much as the Americans,But the English seem to have been talked out of celebrating their own country(via the patron saint)by the the new lefty establishment,surely the flag could only really have become a potent symbol of the far right after it had been abandoned by the country as a whole?
I believe the English should be as proud of their flag as any other country,England has a lot to be proud of in its history.It probably has a few things to be ashamed of as well ,but what country hasnt.
I notice the Bishop of York on TV today(who happens to be black and afaik an immigrant) saying that England should have a public holiday on St. Georges day.Nuff said.
