I have to admit (being from the USA originally), I do love seeing all the flags flying outside houses. I'm not talking about in Alabama where they also have a confederate flag as a curtain in the front window and a "Make America Great" sticker on the car.... I'm talking about "normal" people in "normal" neighbourhoods. Most of my friends have them, many are former military, current serving police/fire/EMS (or friends and family of them), many just love the fact they live in a free democratic society that can elect a total idiot as president..... Im taking my partner to the USA in a couple of weeks, for his first USA Fourth of July. We will be in Vail where they still have the town parade with parents pulling their kids in little red wagons behind the fire truck and in front of the high school marching band.
I do love how Americans take such pride, and demonstrate appreciation for the lifestyle and liberties they have. I just wish some (now so many) of the whackos didn't take it so far. My mother being one of them, complaining about having to wait so long to see the doctor "cause of all the mexicans". I remind her she lives in California, which was owned/occupied by Mexicans until 1850, and that she lives 40 miles from the boarder.......
I truly think Australia is another of the most patriotic countries there is. Even immigrants like me, take such pride in the culture, the sense of community, and the appreciation for our freedoms (and stand together in the struggle of paying 100% more for Ralph Lauren polos than in the US

)
I remember Sweden having a lot of homes with the flag flying. I stayed at a farm as part of a homestay exchange (ages ago), and the family had a huge flagpole with the Swedish flag on it.
