Flags are different. Flags always have symbolism, that's their point.
Similarly, children can draw a hammer and sickle for fun if they want. However, should you put it on a flag and fly it in front of your house, don't be surprised if people draw conclusions.
Even more extreme: Swastikas in the decorative masonry in a government building? (http://en.wikipedia.org/wiki/File:Greca_a_svastica_-_palazzo...) Don't expect much controversy. Swastikas on a flag in the same building? Expect an issue. Something being in a flag or not is an incredibly important context that must be considered.
The University of Hawaii has several names for its sports teams, some of which are The 'Bows, Rainbow Warriors, and Rainbow Wahine.
Can’t you see quite clearly that in the story you are linking to the bigots are the problem, not the symbol?! Isn’t that obvious?!

Words change meaning over time. People create logos and symbols to represent their ideas and points of view. When corporations do it to sell things, it's called branding. When we do it to try and get treated like equals by society, it's called "appropriation". Sigh.
People who put flags on their house because they like the pretty colors are as tasteless as someone wearing a black armband because they think their outfit needed an accessory.
More specifically, its a circle. Though usually you can;t see the whole thing.

The original flag had eight colors, two more than its customary version, each representing an aspect of gay life: red for life, orange for healing, yellow for sun, green for nature, blue for harmony, and violet for spirit."
"In 2006, a straight family in Kansas had to defend flying a rainbow flag at their bed and breakfast from some angry townspeople... Understanding the wider symbolism, the owners nevertheless chose to fly the flag because their young son said it reminded him of the movie The Wizard of Oz, evoking the movie's signature song, Over the Rainbow."
