Then... what do they mean? I mean some of them like "thou shalt not kill" and "thou shalt not steal" are pretty cut-and-dry.
You'd think so, but you're wrong. Theists can twist even the simplest of sentences to suit their own SPAG.
Anyway, Mr./Ms./Mrs. #2761, there's a very simple way to prove the Bible is repulsive: just read it. And I mean
all of it; not just the bits you hear about in church. After you do that, the next step is finding who/what to worship is simple. You can choose the almighty jug of milk, which will answer any and all prayers with either "yes", "no", or "wait", or you can worship Me. I do something no other god in existence did, does, or will do: I will interact with you (during specific hours of the day). That said, I do answer most prayers with "no". It's a trade-off you might want to consider.
