Just a few things to add to your observations Lapis. First of all, before WWII the swastika was used on Coca-cola advertismeents nad beverage cans, the swastika was also used for hockey and tennis teams, several household products, countless religious purposes, and even a boy scout badge.
Second, some might equate the white and blue flag of Israel as equal or greater to the tyranny of the Black White and REd flag of the 3rd reich.
supremist symbolisim is not isolated to the swastika or the sig lightning bolts, here is a link to FLAGS OF THE WORLD neo nazi symbolisim sub-website http://www.crwflags.com/fotw/flags/naz.html .
