For certain anime like historical settings the lack of representation makes perfect sense, however other mediums like Isekai or scifi settings it makes the setting seem shallow.

We see more beast people in anime than black people for example, please note Im only comparing representation and nothing else.

That’s not exactly inclusive.

Where there is inclusion it’s often racist stereotypes.

I found AoTs inclusion of Onyankopon to be fine and even, if very briefly, touched on initial reactions by cultures that have never encountered people of another skin colour before which I liked.
