Let's put our cards on the table and ask the important questions towards theists.
What do you believe and why???
Should be pretty straightforward..........(apparently)
PS, lots of random bullshit to come
The question of what you believe and why is actually a very good question, and it should be the starting point of any discussion on this subject.
What you shouldn't do is then pass a flippant judgement on answers you have not received yet.
The question can be answered in a basic way to begin with, it doesn't require a single line or paragraph to answer it in it's entirety, it is a means of starting a discussion.
Here are perhaps some more specific questions, which god do you believe exists ?, what are some of it's attributes ?, did it create the universe ?, does it interfere in human affairs ?
And then of course comes the why do you believe this.
