I am sorry that you have, but that isn't enough reason to blame all intellectuals (and preachers, family members, and big business [hell even docs] might not be intellectuals depending on who it is). You have been mistreated by people in general, not just intellectuals. And that is unfortunate, but it is not reason to hold a grudge against an entire set of people for the mistakes of a few. That is the very sentiment that fuels racism, sexism, etc.
And through it all it stands that the world is not completely intuitive. Anyone who has taken a intro physics class or who might have been born not knowing the world was a sphere probably knows it. That is most of us.
