The author makes an excellent point; at the founding of their creed, their scripture demanded they be armed at all times.
Unfortunately, having a dagger at the ready is a bit outmoded.
In fact, in light of the march of history, and of recent events in particular, they might want to rethink their governing philosopy and require that all Sikhs, at all times, carry a quality semi-auto and know how to use it.
Maybe some enterprising gun company could name a model of handgun “The Kirpan” so the Sikhs can do both.
