They didn't want to be part of you.
They didn't think you're right. In fact, they think you're wrong.
They have different values from you.
Now, since then they've largely assimilated in order to be like you, meaning that they think you're right and have mostly the same values. So I heard tikkun olam, put in completely secular and non-Jewish terms. It's rebuilding the world, but the speaker had in mind not anything like a traditional Jewish view but an entirely secularish, progressive, humanistic view--making tikkun olam the same as any other new-agey sort of "let's all get along and make for a perfect world". It's one of the traits that's easiest to repurpose--from making the world righteous before God and at one with God to fighting racism, sexism, the patriarchy, etc., etc.
But as soon as they step out of line, like everybody else, they're not part of your group, they don't want to be part of your group, and, if, in fact, they think your group is wrong and judge your group then, well, you don't like them. Whether they're anti-vaxxer Orthodox or the idea that Jews should have their own territory where they can be safe (a bad thing, unlike the idea that others should have their own territory where they can be safe).
That doesn't describe just and only anti-Semitism, but it is where it started a couple thousand years ago. Rome had no love for the Jews. They refused to be part of Rome, to assimilate to being Roman, and fought being Roman. After that, we have stereotypes and it's habit.
Along the way, among those who are more paranoid, is the idea that somehow they're all conspiring for power over us. Making for a weird dynamic--they're more cunning, clever, and powerful than us. At the same time, they're inferior, stupider, crasser, and worse than us. Tribal thinking both exalts the community as well as is fearful. It's often a horrible thing.
