Yes, just caught the threat information.
FWIW there is a major hindu temple in Pittsburgh. Seemingly nice folk although a fellow who used to work for me complained that he had worked for a cleaning company that was hired by the temple.
He claimed...again FWIW...that the cleaning crew was not treated with respect. They had been hired to clean up food left in sacred places so the gods could eat. Food was left to rot. Then his company was called because the priests needed “the unclean” to address the situation.
Keep in mind the source. This is not a sikh temple as far as I know.
There is/was a hindu temple in WVA that was similar and turned out to be basically a scam.
FWIW on of the founding beliefs of the Sikh was opposition to the caste system.
