It's kinda the other way. Everybody has morals and ethics in one form or another, because everybody has religion, even though it may not be one of the formal religions.

EDIT: To see that this is true, consider all the people of a particular formal religion. No two people believe their religion in exactly the same way. Usually they formally claim that they accept some doctrine that the leaders proclaim, or that is in some religious books. But because they all understand it differently, there are simply a bunch of people with their own individual religion that happen to go under the name and banner of a particular formal religion.
It's like this with all the people in the world... except that some don't have a religion that is formally stated to be a religion.

Word Origin
C12: via Old French from Latin religiō fear of the supernatural, piety, probably from religāre to tie up, from re- + ligāre to bind
Only some of these definitions agree with your definition of "religion" whereas all of them agree with my (atheism excluding) definition of religion.
Your dictatorial-like suggesting of what other people think doesn't work. Nobody knows what other people think... except God, of course. So, in your brazen suggesting that you know what I think, you are essentially suggesting that you are God. Fine attitude for a self-proclaimed atheist.
Of course, when a person looks at the definitions of religion above, from http://www.dictionary.com/browse/religion?s=t, it is easy to see that atheism falls into the definition.
Since your definition of "atheism" doesn't fit the above definition by your own words "... (atheism excluding) ..." why don't you call what you are saying is atheism according to what it really is? Oh, that's right. You can't. Why not? Atheism is self-defeating. It doesn't exist. Atheism is an oxymoron, if for no other reason than an atheist can't believe that God doesn't exist, because there is too much evidence in science and nature that shows that God exists.
What is an atheist doing if he isn't and really can't be an atheist? He is setting himself up as god, against nature and science. No atheism. Simply lying self worship.
