People who don't know what irrational means
If you have an irrational hatred of something, it doesn't require justification as that hatred is subjective rather than rational.

I hate people who don't understand irrationality because it makes me really angry.

Partially correct.
However, the degree of the hatred can be irrational.
For example, I have a hatred of most Ministers for Work and Pensions.
I have a rational basis for this hatred.
However, the degree of this hatred is irrational, and it does not make sense for me to have elaborate plans to murder them all in their beds.

(This murdering can be appealed against by submitting an appeal, see leaflet GL24. Any appeals must be submitted in writing within 30 days of the date of the murder)

Surely...
... an irrational hatred is one that cannot be written as the ratio of two integer hatreds.

This problem is built in to the question
Since "Irrational" & "...and why" are mutually inconsistent.

If we're not careful, the computer that runs this world will suffer a logical paradox, and will shut down. Which would allow Kirk to shag the pretty native girl, so it's not all bad.

Bollocks
Definition of irrational

An hatred with a justification may be irrational if the justification given doesn't rely on any Reason (reasoning, logic, commmon sense etc.)

A hatred of cheese because of all the little Martians that live in it is perfectly valid on this thread, because even though a justification is given, that justifcation is devoid of reason (if you follow me - "because it's bollocks", if you don't).
