The quotes from GfS, all of which were written by believers in an attempt to discredit those who disagree with them. None of these are pertinent to anything. Slogans and catchy phrases seem like a good description.

If there were no God, there would be no atheists. --G.K. Chesterton
Of course not, there wouldn't be any need. So?

Nobody talks so constantly about God as those who insist that there is no God. -- Heywood Broun
Simply not true. Add up all the sermons in the world and compare to them to whatever is said by atheists.

In some awful, strange, paradoxical way, atheists tend to take religion more seriously than the practitioners. --Jonathon Miller
Again, simply not true. Most religious folks are very serious about it. Most atheists really don't care that much.

It amazes me to find an intelligent person who fights against something which he does not at all believe exists. --Mohandas Gandhi
Bad semantics. Atheists, on the rare occasions that they feel like fighting about it, are fighting against the harm that is caused by belief in god, not against god.

Some atheists express their rage against God although in their view He does not exist. --C. S. Lewis
Exactly the same as the Gandhi quote. Rage? Compared to the rage of many religious folks?

If atheism spread, it would become a religion as intolerable as the ancient ones. --Gustave le Bon
If atheism became a huge, organized, powerful entity - on the order of the Catholic church or the US Government -- that might be true. Every large organization has power-seekers and corrupt people. Show me such an organization. If atheism itself spread, without any organization, you'd just have a bunch of people going about their lives, pretty much the way atheists behave now.

By the way, GfS, if you can't contribute the conversation without calling people names, perhaps you should just go away. We don't need your hatefulness here.
