I'm actually glad i read the first part first, and didn't stumble on this one first.... cause i would nod in a silent approval, and that would be it. ;)

I definitely lean more towards sharing information (proving points), rather than keeping it to myself, because i also demand the same from others.

People often defend their ideas as if they are part of their identity and well-being (and to some extent it is true in their perception). But ideas need to be challenged or they (and we) can't evolve - they adapt to the friendly environment of a complacent mind and thrive while simultaneously stagnating.

But you know what, your words, or something of the same vein, should be presented before making any attempt to change someone's mind, because it is often the attitude we bring to the table that gets rejected not the knowledge. So i think it is really important to educate ourselves on how to educate others.
