I think generally anyone who feels the need to hang flags up on their home is a rabid nationalist. Different story if they hang up flags from other countries but it’s always a political statement.
Yeah, I was being fafetious. It's definitely a sign of Nationalism and Patriotism, especially in the US. I also think many that do it over there are ex servicemen and women.
There's a guy down the road from my lad and he flies a different flag every week. I think he's got a Swedish one this week, Canadian last week and Malaysian the week before. I've always wanted to catch him raising or taking one down to ask him why as over the years I think he's pretty much flown every flag from every country in the world. It's always a wonder with me and my son trying to work out why he chose that particular flag each time we drive past.
