We shouldn't assume different kinds of prejudice are equivalent, or to try to set up a fixed order of how bad they are.

How harmful any given kind of prejudice is can vary from place to place, and over time.

For example, antisemitism in the US was much worse before World War II than it has been since the 1950s. My mother told me a story about her childhood in Brooklyn, about childen from of Catholic schools screaming "Chris killer" while running after Jewish children — every year after Easter. The rest of the year they might be friendly.
