despite my personal views and the fact the religion in history has been the cause of many conflicts/ wars/ deaths... ect... I don't think our civilization as a whole is ready to all be athiests right now..... some can handle it and some cannot..
I have my doubts that these maladies were 'caused by' religion as much as religion was used as a tool to promulgate them. Economics and politics probably should fairly take a lions-share of the blame in most cases. This is a new-ish construct for me; for most of my life I was prone to take a more simplistic approach to assigning blame (on religion most usually.)
