Look at what happens during typical "Sikh" wedding festivities. These "Sikhs" are the majority (greater than 90%) whether they identify as "reform Sikhs" (or have even heard of the term) or not.
It's quite silly of Hindus to start provoking Sikhs in the West, they won't exactly have Modi saving them.
I wonder how interfaith families deal with these tensions? like Sikhs with Hindus partners/spouse? they probably just bury their heads in the sand, I guess ...
