we have a guy out here who has built a ww2 motorcycle with a side car and has the Eagle on it, he comes out in a full WW2 nazi officer outfit complete with swastikas. No one gets offended.
Now if he were to say wear this and drive his motorcycle to the jewish temple and sat outside yelling "JUDEN JUDEN!" ... well than we might have an issue with it.
On a side note the swastika actually has a noble meaning, unfortunately hitler associated with his Kampf.
