I was born in Walsall, England where was (and probably still is) is a Sikh temple and a thriving Sikh community. They are good neighbors, hard working and honorable, and with equality and charity a living part of their religion, not something that they pay lip service to like so many Christians. Feeding the hungry is a fundamental par of their religious observance.
My mother was manager for a medical practice. Her only complaint was that they all had the same last name, which made alphabetizing the medical records harder. The filing system had a whole drawer just for Singh (Lion) for the men, and Kaur (Princess) for the women.
The idea of someone going in to a Sikh temple and killing people for no other reason than they are different and wear turbans and headscarves hit me in a visceral way. Fuck that.
