Why the invective? It's because "[w]e know that millions of good people cherish their delusions. We don't care; that a lie makes people feel good doesn't make it a truth."
There it is in black & white. They don't care!
I just don't get it. How can these militant atheists insist that they are morally superior, and behave in such an obviously relationship-denying, trust-destroying, character-damaging manner?
To have a harmonious community - be it a family, a local suburb, a city, nation, or world - we need people who behave in a way that builds personal trust and relationships. That is, we need people who genuinely care about each other. These militant atheists don't care. Correction: the only thing they seem to care about is rudely and violently imposing their beliefs on anyone who remotely disagrees with them. So I don't trust them to have healthy relationships or build healthy communities.
This concern of mine is not, I submit, a purely Christian one. I think it can be shared by anyone who's not as bombastic as the new atheists - including non-bombastic, open-minded atheists. The media response to the Global Atheists Convention is a case in point.
