But xenophobia is not class-based, it can be aimed at powerful people (and be partially justified) or aimed at powerless people. Anyone can fall for it, look at the recent example in South Africa: www.bbc.com/news/world-africa-66808346
I’m just trying to figure out where to draw a line for an acceptable amount of useful self-defense xenophobia (a sort of protectionism) as a general principle e.g. legislation preventing foreign countries from owning any of your critical infrastructure sounds reasonable vs self-destructive xenophobia e.g. “those damn foreigners”
