It’s mainly the case because Grinnell is one of the few LACs with generous financial aid for internationals. I was recently talking to an Asian international who transferred away from Grinnell partly due to racism, and he cited the domestic students’ apathy towards most international students’ issues (as highlighted in the article I linked). He also mentioned that most non-white internationals feel very uncomfortable among domestic students at Grinnell.
Read the article again. The Asian Grinnell students highlighted that anti-Asian hate crimes at Grinnell in the wake of COVID were unsurprising because the school has a long history of not being inclusive to BIPOC.
Again, anyone with more questions about this should feel free to PM me. College Confidential does not do a good job of showcasing the downsides of SLACs to POC students.
