I'm am an Atheist, but do not choose to simply define myself by what I am not.
What I actually AM is a Humanitarian. I can and do read many an opinion, and philosophical writings, and traditional best practices. I can, and do take from any good idea, standard, etc...that is good. That includes religious books, like the Bible. Much within many books is laudable, and much of it is horrid, just like any other possable philosophy, beliefs and practices.
Good ideas, and actions can be found within any culture. Religious people, although they promote the idea as such, are not the only people with mercifully compasionate hearts, that value family, love life on our wonderful planet we call home, nor are they the only people who hold Good will towards their fellow Earthlings.
Atheists continue to survive and thrive, dispite being THE most maligned, and persecuted minority group in all of history, and the world to date. All because they do not fall in line according to the dictates, and dogmas of the world's religions, traditions and beliefs.
