I like this response to the Wisconsin Sikh temple shooting last Sunday:
"That perpetrators of such crimes mistakenly believe Sikhs to be Muslim reinforces the fact that ignorance lies at the root of racial and ethnic hate...Each of us bears a responsibility to reject hate, whatever its form, whatever its justification. A soul filled with hate can devastate a community. A nation filled with hate can devastate a people. It must start and end with each of us."
