For most Jews, Judaism is more than a religion. It's core to our identity for many of us. All of the Jews who died in the holocaust didn't have a choice to just stop being Jewish.

To be clear: I'm not trying to compare being Jewish to being Black. I'm saying that I can draw empathy from the Jewish part of my identity toward other people who have been mistreated because of part of their identity.

Also, even if it were a choice, I would no more give it up than anyone else should have to give up their race or ethnicity or any other part of their identity just to fit in.
