If there's one person that sticks it to the christians unquestionably, then that's PZ Myers. The 800 pund gorilla of the Atheosphere Fear the Cracker!

One of the best and most solid ethical theories around. Although the blog is very simple, the content is great. If you are wondering how an objective moral system can exist without a higher power, then this is for you.

An excellent pundit with many insights on Socioeconomics, Politics and Religion. Don't get on his bad side though or you'll be intellectually skewered ;)

Very well articulated and to the point articles on many subjects, from Religion to Economics.

Not really a good blog. Closed now because of extreme suckiness
