The image of the khanda is a sense of pride to the Sikhs and a symbol of their faith, no doubt.
At the same time, it is also a representation of the Sikh religious doctrine. While it is the official representation, it is also an arbitrary rendering. It is not decreed by Sikhism. The Khanda has not always been around in Sikhism. The official symbols have changed over the centuries. Similarly the official symbol of Islam is not the star and the moon. These are also man made symbols. There is no Islamic decree that this symbol should represent the religion. My point is, theologically, the Khanda is a representation of the Sikh faith, and THIS is what makes it important, not because it is tatoo'ed on people's arms and because it is the most identifiable symbol to Sikhs, or because it is written anywhere in the Sikh holy books that there should be a Khanda.
By APD chanding the symbols to reflect their team name two things have happen.
1. they have deleted in part the representations for which the Khanda was made for.
2. They have (it can be argued, disrespected) a symbol, and religion that I am sure that set out to highlight with their symbol.
In the hopes of this not turning into the POL Khalsa Junction debates, I hope that we can be constructive and understand APD's intent. At the same time, I totally understand why people are offended. While I would not be offended if someone modified the star and moon, (because these are not religious decrees), the Khanda is a direct representation of Sikh principles and thus, I do not believe it should be altered.
