Why is racism wrong?

[Mister Agenda]

Proof for your assertions, please.

But I have not, so far, made any assertions.

This:

"First, racists often rely far more extensively on empirically derived facts than their opponents do. That is, racists don't "just make it up" and then rantingly insist upon their narrative. Instead, they do quite a bit of research before they write."

is an assertion. You're not off to a very good start.

Edit: Of course, I see I wasn't the first to note this.
