I really don't know what she expected - but as you pointed out in your earlier thread targeting someone's family is low and deserves utter disdain and as little publicity as possible.
People have to claim responsibilities for their actions just like the suicide bombers.
Yes we know their parents and families sometimes aren't involved but people must understand the repercussions of their actions will bring forth many angry and psychotic people who if they can't get at you they will attack your friends, families, property buisnesses and pets!
Whilst it is understandable she should receive strong criticism I'm not sure why "online threats of murder and rape " should have been expected.
She is lucky that she is allowed to protest in this way without being charged. The outcome was rather different for that man in North Korea who was imprisoned and ended up in coma (and then died) just for taking down a poster
I think what she did was deplorable but should the trolls of the world threaten her with death and rape ?
pick on her and her family?
What is happening to humankind?
