Are those Atheists Jewish bankers?
You can't be Jewish and an Athiest, ya neo Nazi dickhead.
Of course you can be an atheist and a Jew.
I am essentially (I don't want to argue the semantics of "atheism") both of those things.
Nope. Can you be a Christian and an Atheist?
I don't know if many people identify as such, but sure. In fact, I would guess that most "atheists" in this country have a Christmas tree, exchange gifts tomorrow, and have various other traditions based on the religion they left behind.
I am Jewish because my mother is Jewish, and so is her mother, and so on. I am Jewish because my great-grandmother left her shtetl in Poland and got on a boat. I am Jewish because I was raised to think of myself as a Jew.
I am an atheist because I was raised (by Jews) to not believe in any "God". I am an atheist because my grandfather was a scientist who broke boundaries and discovered things that no one knew before him. I am an atheist because that same grandfather wrote his own haggadah, assigning scientific explanations for all the "miracles" and "plagues".
I am Jewish because that same grandfather couldn't get a job under his given name, and had to change it.
You are correct, mostly, Jew can be a culture, a people, and a religion. It can be one, both, or all three depending on the person. When it comes to Jews, however, you can be a Jew racially, but if you aren't following any of the traditions, tenements, or rituals of the religion whatsoever, then technically, you aren't a "Jew". I have a close childhood friend who like you, was born a Jew, but due to many difficult events in his life, never believed in God, and went on to marry two Christian "White" women and have kids from them. Therefore the only "Jew" in him was the fact that both his parents were Jews.
I on the other hand am what one might call a very secular Jew.
That aside, all I'm trying to say before the antisemite injected his bigotry into the discussion is, as many if not more people have been killed by Atheists, most of them not born Jews or affiliated with the people or religion in any way.
