"Why are the college kids and Israel = apartheid folks so limited in their repertoire? Are there no other countries worthy of financial boycotts or condemnation based on moral or ethical failings? (obviously excluding the Russia situation)."
Why excluding Russia? That doesn't count?
Let's see... We have sanctions on Iran, Myanmar, Cuba, Syria, Venezuela... North Korea. Not Israel though. Certainly not Saudi Arabia... But individual people are clearly allowed to decide whom they will and won't do business with. And states passing laws to punish them for it is so blatantly unconstitutional it makes my head hurt.
"Jews in various countries get attacked when Israel misbehaves."
Well, that's just wrong. It's wrong when it's done to Arabs or Asians too, and it is... a lot. But nothing about it justifies your conquest and occupation of someone else's lands, or gives you the right to abuse human rights.
If you had any sense of fucking shame, you'd understand that.
The UN granted the creation of Israel, and people can argue the right or wrong of it, but it's a fact. They sure as hell didn't sanction the conquest of the West Bank or Gaza or the Golan heights or even the Negev... and certainly didn't grant anyone the right to subjugate the people who lived there for centuries before you came.
You should never be ashamed to be a Jew, but this crap? Are you really willing to be this?
