From my experience there is a lot of lack of education in the population of my area and US, maybe others too, but in terms of understanding emotions.
Having emotions is not a rational or irrational thing, it just is. It takes time for the mind to "rationalize" or process emotion, in some cases is unable to for lifetime.
Emotions don't come because we want them to happen, they happen due to unevolved ancestral instinct that used to save our skin, bad experiences etc. We might not be in danger with our life like cavemen chased by the tiger but we feel just as though we are, even if we're just having an unpleasant experience. Equating the attribute of having emotion to your rational abilities is nonsense. It happens a lot, though, where people say, its irrational you feel x. But that's obvious it is, because feeling is irrational in nature, it doesn't exist because I've thought about whether it should or not happen. I don't choose my emotions.
However I might be able to rationalize some events in a way that allows me to be less scared about them, lessen them or have more preparation when they come. Therapy work.
