My own opinion is...there are many types of atheists, just like there are many types of religious people.

Here we go again with the tired old equivalence thing. Well if you mean that there are many religions, therefore many shades of believer, OK, I'm up for that. But atheism is not equivalent. You invented us by having religion. We are not actually here. If religion miraculously disappeared tomorrow there would be no word "atheist" yet not one of us would have done a single thing to change anything. There are not different kinds of us. There are not any kinds of us. You invented us and now you want to patronise us with some kind of faux-taxonomy. Bring us into your fold by embracing us with a classification of your making. No way!
