I understand peoples’ discomfort with the Sikh’s kirpan . . . but I tend to have a much higher opinion of their religion then I do of the vast majority of Christianity.
The Sihks have a religious obligation to feed people facing food insecurity (a process that they call “langar”), and they do it without prosthetylizing and/or passing judgment.
Everybody is allowed to come and eat, with the only requirement that all conflicts get left outside so that everybody may eat in peace.
As far as I’m concerned, they can carry all the knives they want when they feed people as much as they do.
