"So, you believe that God does not actually exist, but his believers have imparted this mythical character with loathesome characteristics, and either manifest those character flaws or use them as some sort of tool over others. I'm not trying to mock or trap you, really.
Yes, that is exactly what I "know" (I have an aversion to the word "believe"). However, I would just substitute "many of his believers" for "his believers."
"Truth is, I don't really KNOW what God is like; I know how I believe Him to be."
As long as you don't think that God believes that: atheists are worthy of Hell; slavery is justified; homosexuals are an abomination; women are second class citizens; only born-agains should be president, etc, etc., then what you believe him to be will not harm or offend me or anyone else.
