Hello, I just wanted to give you a reply about what you wrote from the "Are we too hard on Iris?" topic, and I'm doing here because it might be off-topic as well.
Imo, there's a huge social-cultural difference between the West and East Asia, and I can understand why people are divided about the stuffs shown in the anime. The thing is people in East Asia are not well exposed to black people compared to the West, which affects her popularity and popularity sells over there, kinda similar why Marvel's Black Panther movie was mixed in China while it was universally praised in the West, Chinese people aren't used to see a cast full of black people.
