Why are you (still) a Christian?

The Bible describes a god as anything or anyone mighty or venerated. Examples, Jehovah, Jesus, Satan, Moses, the judges of Israel, angels, Dagon, Tammuz, Baal, Ashtoreth, etc. 

Anti-theist is a good choice. Better than atheist, in my opinion. More accurately descriptive. 

Sorry, sir, but no. 
In Hebrew culture there are many "divine beings" .... when the Witch of Endor conjures the shade of Samuel for Saul in Kings, (which was forbidden ... to disturb a dead shade), she is asked what she sees ... only a witch could see a shade, and she tells Saul that she sees a "divine being rising up". The Hebrew pantheon had any number of "divine beings", but they were not gods. These divine beings lived in heaven with Yahweh, and not in Sheol where all other dead shades lived. In recent scholarship, there are a number of PhD theses written about the "heavenly host" who are all "divine beings" but they are certainly not gods, nor do any of them equate to the status of Yahweh.

You seem to be referencing Jewish tradition which I'm not conversant in. I was referencing the Bible. So, in the Bible a divine being is a god, from the Hebrew el and variations thereof (Elohim, etc.). Anything or anyone mighty/venerated. The spirit, or shade, summoned by the witch of Endor was a deceptive, demonic spirit being. Nothing lives in sheol, sheol is the grave, corresponding to the Greek hades.
