Since you choose not to tell me how a progressive anti-Semite would tell people he hates Jews, I assume you have no good answer for that question. The most charitable interpretation I can think of of your point is that a right-wing anti-Semite is more likely to be open about his hatred of Jewish people; that a left-wing anti-Semite is more likely to express his hatred of Jews through the three D's: delegitimization of Israel; double-standards for Israel; and demonization of Israel. He might not even be fully consciously aware that he hates Jewish people and is likely to deny it if asked. If he is asked why he criticizes Israel for some isolated misdemeanor while ignoring other countries which systematically engage in felonies, so to speak, he will not have a good answer.
So where does that get you in terms of your original point that people are more rational now than in the past, and anti-Semitism is an example of this? Well certainly people in the West are less likely to express hatred for Jews or to organize pogroms. But your example of the left-wing anti-Semite shows that there is still a good deal of irrationality in play by your own standard. So again, it seems you are assessing rationality by measuring conformance with modern progressive political views
For reasons I have expressed elsewhere, I think this is a bad idea.

What in the world are you talking about? You are aware, I hope, that "progressive" is a euphemism for "left-wing"? The example of left-wing anti-Semitism shows that a reduction in anti-Semitism is not in conformance with modern progressive political views.
Suppose I told you that I knew for a fact that the following statements were true:
You’d think I was crazy, right?
Now suppose it were the year 1901, and you had to choose between believing those statements I have just offered, and believing statements like the following:
Based on a comment of Robin Hanson’s: “I wonder if one could describe in enough detail a fictional story of an alternative reality, a reality that our ancestors could not distinguish from the truth, in order to make it very clear how surprising the truth turned out to be.”1
