Author should look up what the word "condemn" means. They don't seem to know. I love Bernie just as much as the next guy, but if you don't condemn Israel, then you don't condemn genocide. Period.
I, personally, don't care at all for the politics of another region. I just plain don't care. If they want to kill each other until no one is left, then that's their own prerogative and I don't care. But that's not what's happening. Israel is systematically expunging an entire group of people from the face of the earth, a group of people who don't have the means to protect themselves. That's genocide, and there is only one valid moral stance when it comes to that, and it's to be against it. If you're not against it, you're complicit in it. Period. There's no moral wiggle room when it comes to genocide.
The Jews of that region are totally fucking insane. In many ways far more insane than even the Germans during WWII. Unlike with Germans, Israel believes that the extermination of Palestinians is ordained by God and not just a national point of pride, and that's why they won't stop. It's like they all huffed too much Glue and now they're all just fucking crazy.
It's interesting because they think all Palestinians are terrorists and like most developed nations, they created their own terrorists. They pushed this group of people to the breaking point to where their only outlet for resistance was terrorism. It's such an obvious parallel with the US and the middle-east. It's crazy.
But whatever. Bernie doesn't score any brownie points with anyone for his stance on Israel. If anything, it hurts him significantly. It's going to stop a lot of people supporting him than he would otherwise have.
