Since...you want to eliminate us...
Whoa, whoa, hold on. Who the hell ever said such a thing?
...why can’t we just eliminate you first?
Religious folk tried their best to do just that. Consult any history book. Hell, consult your own Bible (I'm assuming that you're a Christian).
Isn’t that what Hitler did to some 10 million people he felt did not contribute to the plan he deemed best for society?
No, actually, it isn't. You're claiming (wrongly) that nonbelievers are trying to "eliminate" believers. There is no analog of such behavior for the Jews in Germany during Hitler's rise to power.
Put simply: your analogy fails.
By the way, Hitler exploited religious prejudices to unite his followers against a hated minority. Sound familiar, Ben?
(Let the record show, I am not advocating, merely asking.)
You're "merely asking" a loaded question. It's like asking if you still beat your wife; the implication is that nonbelievers don't have a moral compass.
Let me put it another way--if the voice of God commanded you to kill somebody, would you do it?
Is what Hitler, Mao, Stalin did “wrong?” Why?
If you don't think that it's self-evident that killing tens of millions of innocent people is inherently wrong, then there's very little hope that you'll understand my answer.
