>>there are quite a few pics in the gallery that I (and many fellow non-Americans) find just as disgusting (like all the 'stars'n'stripes' in peoples' frontyards)<<
I must say, there is a documentary/photojournalistic element to these flags. They are pervasive in the United States and so are part of the American landscape. They do not symbolize support for any particular American political leader or political party. Rather, they affirm an American ideal that most of our political leaders fail to achieve.
I would say all cultures have baggage that is perceived differently by other countries. I was absolutely thunderstruck when, as a very young American soldier, while stationed in West Germany, I attended a German-American military ceremony and heard the German national anthem played by a German military band. I had no idea "deutschland ueber alles" was still the country's anthem, and to me it conjured up so many symbols of oppression and national failure. Germans hear one thing, some Americans another.
Having traveled to more than 40 countries, I'm well aware that the American flag is not welcome everywhere. My country has a sometimes terrible history. I grew up in a state ironically called Indiana, even though its native inhabitants had long ago been driven away by genocidal policies. More recently, our military forces were restricted from helping in the aftermath of a devastating hurricane because of an 1878 "posse comitatus" law that prevents the military from enforcing law and order and which was originally passed to prevent U.S. troops from protecting Black Americans from voting in former Confederate States. Still, we have an American flag in front of our home in the American suburbs today. And it sometimes shows up in pictures I take of my children. Looking at this flag, you can't tell that the occupants of the household have differing political views. You can't discern which occupants of our home have a Christian, Jewish or Muslim heritage (we manage to mix all three) or that they or their parents were born in several different countries. What the flag expresses, in front of my house, anyway, is that we belong to this country, we embrace what is good about it, we try to learn from its mistakes, and we're going to do what we can to improve what we think is wrong with it.
In that respect, the stars-and-stripes are quite different from the Swastika, which has been universally condemned as a symbol for uncivilized conduct with no worthwhile ideal.
Within the United States, the American flag is a fact of life. Trying to keep it out of photographs would require a conscious act of nearly constant censorship that would, in itself, be a political statement.
