No, Coyote - rocks thrown at cars are not ALWAYS 'terrorism for an ideology' - but if you've had it happen, you'd know it inspires terror. And this was not ONE rock, nor ONE incident.
Rock throwing is common.
But here is a key difference: when Palestinian kids throw rocks they can be met with live ammunition and murdered. They can be dragged from their homes in the middle of the night, subjected to physical and mental abuse and prevented from seeing parents or lawyers.
When Israeli Jews throw rocks: IF there is any police action, parents are involved, rights are respected and legal help is immediate. They are never interviewed without a parent or guardian. They seldom go to jail. They are never met with live fire.
Big differences in treatment. Big differences in reporting too. When a rock throwing incident injures an Israeli family - it's all over the news, we know there names, pictures, grieving family members. Not so with Palestinians.
