You're admitting that there's nothing that could be provided that would convince you otherwise.
It's tough to understand how you wouldn't recognize that as a problem. What if there was "nothing that would convince you" that racism was wrong? Can you see how that might become an issue?
You're admittedly unwilling to consider any evidence provided, it's automatically already dismissed.
The scientific consensus, that is 100% of every single national scientific academy that's provided any statement on the issue, is clear. Like I said before, if you deny it at this point, I don't know what to tell you. It's just like denying evolution.
