I understand that not all self-proclaimed "atheists" behave in this manner, but to those who do...    

     Let us begin with a brief deconstruction of the word, "atheist."  It comes from two Greek roots, the first root being, "a-" meaning "without" and "theos" meaning "god."  Now that we've discovered that "atheist" means "without a god," let us evaluate this statement.  No where in the meaning of "atheist" does one find any reference to Christianity.

     Which brings us to the crux of the matter.  My challenge to anyone who calls himself or herself an atheist is to disavow all religions equally.  I challenge you to criticize and smite with the undeniable power of logic all "irrational belief," as opposed to just denouncing whatever religion will make you popular.  Let's try to maintain some ideological purity, shall we?  If you hate Christians, don't say you oppose religion.  Say you oppose Christianity with every moral, intellectual fiber of your being.  If the goal of atheists is to hold oneself to the standard of reason, then do so.  If you are anti-Christian, but Buddhism, Hinduism, and New Age belief is fine, then admit it!  Don't, however, use a term to mean what it does not.  After all, one of the chief criticisms of religion is that it blinds the masses and encourages disinformation, correct?  Avoid such hypocrisy, then.  The irony is unbearable when an anti-Christian posing as an atheist contributes to confusion and falsehood.    

And to repeat myself: I know full and well that not every atheist is guilty of this.

Thanks
