I can't seem to figure out the word to use here. I need a noun that describes the state of (someone) being an outcast, but nothing's coming to mind, and I'm not really sure how I would go about looking up synonyms to a word that doesn't exist.

This is the sentence:

Instead of physical obstacles, both are faced with societal resistance and ______.

I might just restructure it, but now I'm kind of interested. Am I just blanking and missing a really obvious word?
