I said that feeling that American blacks would see the Palestinian plight as having parallels to their fight for justice in America.
Except that a great many Jews played major roles in the civil rights movement over the years. You have it backwards: they saw their own parallels in the blacks' struggle against prejudice. More recently, there's been more bad feeling against the Jews on the part of some blacks. I'm not sure of the reasons for that, but I think they're largely economic.
Personally I think Biden is between a rock and a hard place with the election coming, and with his lifetime support of Israel.
I think so too. But it's hardly just him. As a nation, we've strongly supported Israel since its creation in 1948. At least one of its prime ministers was a (former) U.S. citizen. Other (former) U.S. citizens have played important roles in various Israeli governments. And many residents of Israel are dual U.S.-Israeli citizens.
At first, we all admired plucky little Israel, surrounded by enemies but somehow surviving. But as it got stronger, some in the U.S. began to feel conflicted. Once in the '80s, Reagan refused to send more arms to Israel, something many Republicans seem to have forgotten.
Now, the hardline right-wingers have been in charge in Israel for the past 20 years. And that has an obvious downside.
