Is there a way to express in one word when people attach their personal feelings to a concept or an idea and then become very vehement at defending it because they consider it personal criticism.
As they inject their own semantics and attribute whatever they want to the word. so if you criticize the label or what you think the label refers to, you criticize their instance of the label.
In some way they become emotionally attached to the concept but how to say it in one word ?
Object Oriented Programming is a good example of concept (is it even one ?) where people attach their feelings to it and then feel personally attacked when criticism arises.
