I disagree;
Rational emotions are when you have a legitimate reason for having an emotion. Irrational emotion is when you don't have good reason or evidence to support the feeling.
Now in perspective all emotions are real, as in the experience you have is a real bio-chemical reaction to something. From an evolutionary standpoint it was a way for us to make snap decisions without having to parse it out logically.
So back to "I am angry at my father for hitting me" might be rational whereas "I hate all Men" is not.
You have physical experience with someone hitting you, it was unpleasant, and was a violation, and therefore have every right to be upset at the person who used unprovoked violence against you.
On the other hand, you do not have a legitimate reason to feel everyone that is a man will take unprovoked violent actions against you. You may be having an emotional reaction to the template of how you see a man due to the trauma of being abused as a child.
