I'm aware of that, I was just giving an example of how people could/do look at it.
That's why I said that it's something that needs to be experienced in order to jude correctly, and even then, you might get it wrong.

If that shop owner was racist and was proud for giving lower, "good for nothings" a chance, it would be discriminating to the max.
Now if some other shop owner was trying to atone for the sins of his ancestors, or even his fellow colleagues, that would be an example of humankinds progress.
I'm fairly sure both of these scenarios have, are, and will happen.

We can't really judge who is who without experiencing it or a decent amount of evidence.

My personal stance is, that it is horrid how some people look at it, but they are humans nonetheless, beauitful and ugly in their imperfection.
And I personally think, that it is important to know from where their perspectives, ideas, and hate originates from, no matter how stupid it is.
