Again, my point isn’t that addressing issues related to immigration would make bigoted people not bigoted; it’s that doing so would curb the far right’s ability to expand. By delivering material gains for the working class and leading by example, it’s possible to inoculate the wider electorate against the far right (and the right in general). Immigrants are only one scapegoat in a long line of scapegoats; the real mechanism behind the spread of rightwing ideas is that they provide something to scapegoat for people’s (very real) troubles. Put another way, Hitler didn’t need immigrants.
