Well then

I don't think people are aware enough that the "racism" chapter actually happens even if its their own country

Some foreigners act so stuck up in another country because they're different and act like everyone in that country is inferior to them, Ive seen it happen because I've had classmates who were like that and they used their status to be a bully. However, they're white not african american black. Thats somehow one of the differences there. I think it's more of a wrong portrayal of characters, they should have used a white person as a bully since it's these guys who are usually so stuck up (or maybe that's really just from my experience)
