That’s a weird thing to say. I’d be more worried about whether the refugees will want to go back after the war, to help rebuild the country, or stay in their new lives. As refugees, they may or may not have a choice, but on the other hand, countries might want the skilled workers. The longer the war goes on, the more established they could become elsewhere.
Apu was one of my favorite characters, and next to the rest of Springfield I wouldn’t say he was portrayed as any kind of bad guy. But I think it’s entirely fair to find fault with him and the stereotypes used.
The “This is why we can’t have nice things” guys are the ones who use this type of character to mock people of Indian descent. Having heard about their experiences, I would say that the bare minimum that should be done is involve someone from the community you’re portraying, when creating a character who stands out as someone of that community.
I think the main issue with this is that pronunciation changes over time, in addition to varying by area. So if we keep changing the spelling, written works will became unreadable faster.
But I would suggest that any band names that use umlauts/foreign letters should be pronounced accordingly.
Pay them more, entice more people to work, less workload per teacher.
