Yes, thank you, you phrased it perfectly.
In the first series, almost everyone was white. And then Rick realized this had to go when he understood the simple thing: The series started off as being hope for bullied kids with disorders. Why not extend that to those of different races?
That’s what makes each character unique and the series so powerful, no matter who you are, or what you look like, you can always be a hero.
Unfortunately, people overlook this, either by ignorance or laziness.
