>Racists have emotions, too, and often make decisions based on them
And knives can be used both for murdering people and spreading jam on your bread.
The answer to "racist emotions" are emotions of empathy and love towards the other, and not some objective logic that one can follow to fix racism.
After all, one could always use objective logic to justify racism if one wants to -- e.g. "blacks are involved in a higher percentage of violent crimes compared to their population". That's a totally objective statement, it just skips trying to find the reasons why that might be so, and uses the numbers to justify thinking of them as violent inherently.
