Not just "6 pointed stars," but a yellow six-pointed star with a description of its wearer in a Hebrew-style font in black, sewn to the left side of the outermost garment... yes: most people think of the Holocaust.Apparently, that's what comes to mind for most people who see 6 pointed stars.
And by "most," I mean "virtually every person who has at least a passing familiarity with the history of the Holocaust."
