The master, on the Hitler/swastika connexion:
I assume one of Hitler’s colleagues suggested to him the swastika for it’s definitive value as a good luck charm, meaning “this is good”.
From a design standpoint, I am a designer, I like the look of the swastika. It really is a shame that the Nazi’s took a symbol found in many churches and cathedrals and gave it hateful connotations.
It all really depends on the person. From my life so far, I have met many different people. Some though that I found to be connected with so-called politically incorrect groups had no signs or symbols or anything to allow you to pick them out as belonging to these groups.
Glad I could help you out Anthracite!

I think the thunderbolt will be fine, but I’ll probably never have the guts to get a swastika, especially since I spend a lot of time around Africans and Asians, I’d hate to send out confusing signals.

If you are interested in swastikas as tattoos, and the whole racism connection, take a look at http://www.bmezine.com. Do a search for swastika. There is a person calling himself ManWoman who is covered in swastika tattoos, paints swastikas, has written a book on “reclaiming swastikas”, and has his own website. An interview and a link to his site is provided on the aforementioned website.
