Many liberals are deeply confused about how to respond to the campus protests over Gaza. And I think it’s an example of the confusion liberals are feeling generally over a lot of issues.

I believe much of the confusion can be traced to the assumption that all political opinions can fit on a single line, from left to right. 

For this one-dimensional, one-line model to work, there can only be one left and one right — but there are at least two lefts and two rights. And they’re not different as in further left or further right on the same line. They’re different as in not on the same line at all.

And the difference goes back to the rise of liberalism, accompanied by the rise of an anti-liberal left.
