Given that definition of "immune", I agree. "Immune" just seemed like such an all-or-nothing word to me, I misperceived your meaning.
"Immunity to value judgments allows you to sift through information and compare it to your own, without letting your feelings cloud your actions or responses." -- yep, yep, yep.
You might even say, "Immunity to emotional responses to value judgments allows you to sift etc."
Because I think there can be merit in considering the value judgments of others, as long as you keep a clear view of what *your* values are. Someone else's value judgments can sometimes confront you with a way in which you are *not* living up to *your own* values.
All this is sort of assuming the other person is speaking in good faith and not (consciously or unconsciously) just trying to bring you down.
But I guess that's another reason not to be *unduly* influenced by their opinions in the first place.
