I agree with Bruce_Hedley.  The left didn't tolerate the Shafias killing their daughters, but rather the justice system gave them a fair trial and jailed them.

There are vast numbers of reports of North American men, many of them caucasian, perhaps many of them "Christian", killing or abusing their wives and children, or their girlfriends.  Why decry an entire religious group because of rare extreme acts of violence while ignoring the extreme acts of violence motivated similarly by control issues, wounded dignity, the view of women often as property, and, no doubt, some feelings of offended religious principle.

We all need to stand against intolerance, violence, inequity, and extremism, no matter who is promoting it or enacting it.  We need an intolerance for intolerance, when it is activated primarily by skin colour, ethnic origin, or religious preference.  Our world won't be made better for any of us through hateful exclusion and finger-pointing.
