The swastika had many very good meanings (primarily well-being) prior to Hitler. And, as has been posted, censoring it for the work of one man gives that man (even in death) a great deal of power. I understand why many people hate these symbols, and I don't judge them for it. But educating oneself is key to overcoming their power (IMHO.) Certain religions still use the swastika for its original purpose, and I congratulate them for it.

That said, I appreciate the time taken to show these images. They're fascinating, frankly. While I cannot contribute to their actual origins, I'd like to check back on this thread to see what is discovered.
