No, not at all in fact, atheist openly sponsor Muslims
Do they now? Name one, just one, well known atheist who openly endorses and/or "sponsors" Islam. Since you seem to know more about atheists than they do about themselves then you shouldn't have a problem naming a single well known (In words you can understand that means people that you did not make up all by yourself.) that holds those views, unless you were just Lying for jesus(TM) after all.
and their hatred of America
Muslim =/= Hatred of america, If that were the case then how do you explain the millions of muslims who came to america to escape oppresive regimes? Wait, let me guess.... All of those muslims must really be sleeper agents waiting to strike.
What I find most disturbing about your kind is that you will scream and cry "Persecution!" each and every time you don't get your way, as if you were somehow special, but they you will turn around and mercilessly persecute others for no other reason than that they are different from you and that makes them less than human in your eyes.
Not all atheists are liberals, Not all liberals are atheists, very few liberals are muslim, and liberals are not defined as "people who hate america". In fact I would save that label for neo-crazy far right conservatives who seem to be all about shredding the rights of non-christians and replacing the US Constitution and Bill of Rights with a christian theocracy, the ten commandments, and a Christianity uber Alles mentality.
