While I don't agree with you here on more than one grounds, I think I understand your motivation: to offer your point of view on the topic and then leave or to offer your point of view on the topic and defend it if and only if any counterpoints to that view are posited by individuals who are not unsatisfactorily self-aware NFPs (as determined by you).
That is all I wanted to know, I am not personally interested in the discussion itself as it seems to rest completely on a false premiss.
I don't want to preach or judge people. You asked "why" and this was honestly the best answer I could give you.
Take every opinion as a personal attack. Punish all who think differently. Our cause is righteous. We shall make others comply, no matter the cost.
EDIT: I guess I don't really see a way to communicate with NFPs unless they are aware of the above tendencies. Most of the young ones are not.
So you felt it neccessary to apply that generalisation to me?
I wasn't and am not offended in the slightest. I asked you to share why you thought how you did and you didn't. Your choice. As I said I wanted to know where this perception comes from.
It's not entirely fair that you place this belief upon every NFP you interact with, however with that being said I guess I can't entirely blame you for that it still doesn't justify the attitude if you take it upon every NFP you come across.
