I have heard many controversies regarding the use of a swastika in Stack Exchange network. But all the cases I noticed were clearly using a Nazi swastika. To make it clear swastika are of different kinds:
Jain Prateek Chihna (Jainism Symbol)
The Hachisuka swastika, (a family crest used by the Japanese Hachisuka clan).
Many many such example exit for the use of Swastika which exists long before the Nazis.
The swastika (also known as the gammadion cross, cross cramponnée, or tetraskelion) (as a character: 卐 or 卍) is an ancient religious symbol that generally takes the form of an equilateral cross, with its four legs bent at 90 degrees. It is considered to be a sacred and auspicious symbol in Hinduism, Buddhism, and Jainism and dates back to before the 2nd century B.C.
And here are the Nazi Swastika:
Which are clearly distinguishable. So do we allow the non tilted religious swastika symbol in profile picture and chat? If not, then why? If they are so easy to distinguish from Nazi swastika.
