Not fair. You said "So, those who do not proclaim sufficient support for Israel are called antisemites."
It's people who claim Israel has no right to exist and makes excuses for the Islamofascists who are rightly called anti-semites. Also, people who are selectively against foreign aid to Israel... but you never hear a peep from them about foreign aid to other countries. That's a lot different than people who are opposed to ALL foreign aid.
I once had a brilliant trial lawyer (for what its worth, he was a Jew) say, "In a jury trial a good lawyer never objects on technical grounds, no matter how compelling, he objects in the hearing of the jury that it is not, 'fair.'"
You say, "it's not fair." and I concede you are right. Get me batteries for that magic wand and I will do more fairness for Israel in one afternoon than a Walt Disney matinee.
In the meantime, while you are looking for those magic batteries, I must heed the old trial lawyer who said, "young man, lawyers are not hired to be fair, they are hired to represent their clients."
