The problem is that emotions affect rationality - what is rationality even? You feel confident that your thoughts or actions are rational, but that too is an emotion.
To invoke Godwin's Law, the nazis were rational in their policy of exterminating certain people, they listed the traits and stereotypes and decided that the best course of action was to isolate and exterminate them. The US is rational in their policy to label terrorists as 'enemy combatants' and not respect the Geneva conventions when it comes to those.
Yes, underneath those is a certain type of hatred, the emotion, but for all I know that emotion is applied or assumed after the fact - that is, "surely they have to really hate someone do to that", instead of having to admit that it was a rational decision. I don't know which is worse, treating someone badly out of emotion or out of rationality.
