> 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.
