They have a defect in that they can't separate themselves from their opinions. So, if you disagree with their opinion or theory, it's like you're rejecting them personally. Being emotionally crippled is sad.
That used to be my belief for a while, but then I realized not everyone can actually help that they feel about it the way they do. For some people it's more of a natural thing... similar to when I tried to go to school as a social worker, I figured out that I lacked empathy and all to engage in the required social interaction, I just felt that it wasn't in my nature.
In general I don't want to put people down, but I've noticed that some people just blared out what was on their mind emotionally and didn't even attempt to get a rough outline why someone has opinion X on it, and that this, just as well is, just an opinion/view.
