...That's why I don't understand why people can't just talk get their opinions out and people talk nicely to them help them understand their side so that that may be they can come up with their own a new educative outlook on things...
From my point of view: It happens the same as with the fans of some popular sports team. They defend their team as it is and for them, their team is never wrong since they are blinded by an ideological cloud.
That is why when the moment of debate comes, at the least sign of disagreement they will always respond violently, but always of you and never of the idea that is being debated, they are under constant fear since their ideas are fragile and incapable of defend themselves alone as they pretend.
We have to remember the principles of a healthy discussion: The discussion exists so that two parties with different points of view can find the common arguments.
It's not about being right.
