Hi Daniel, Judaism explicitly states, "It would have been preferable had man not been created than to have been created. However, now that he has been created, he should examine his actions that he has performed and seek to correct them," Christianity and Islam strive for imaginary heaven beyond this world, and the main goal of Hinduism and Buddhism is to escape from the cycle of rebirth (ergo to stop being born again). Similarly, secular thought is today predominantly existential or outright nihilistic. As you can see, that encompasses pretty much the whole of humanity and its applied philosophies with their strong escapist tendencies. So much for where I got the whole idea.
Though you may be correct that the wrong view that this "world is an imperfect and corrupted realm" is at the root of such (mis)understanding, I disagree with you on the basic premise -- this realm is neither corrupted nor imperfect. It's just general lack of knowledge that makes it appear so.
As for my existential crises, thanks for your concern but I left them behind a long time ago. Thankfully. You are correct, though, that I "attack" people around me, however I would call that "stirring the preconceived notions." I simply chose to be among the people who need that the most as well as those who are willing to let their old manner of thinking be stirred. Whether you call it compassion or lack of thereof is, frankly, quite inconsequential to me. It is what it is and some things simply have to be said.
