I don’t have to do anything. (I would expect them to be offended just because I don’t believe.) It’s their problem. I’ll just go my way.

Ah those 'faithfools' so ready to take offense.

Turn and walk away, or laugh.

Nothing

Smile and go on with my happy life.

Nothing...not my problem

nothing. why should i? it's not MY problem, is it? but are you talking about a question i make of a believer's belief? why should i question a believer's belief? people have a right to be stupid, or do stupid stuff, as long as it doesn't interfere with anyone else's rights. if they're not legislating, adjudicating or executing their religion, i don't care what they believe and i don't interfere with it, not for fear of offending someone but because i don't care. it's none of my damned business.

I can't imagine anyone getting offended by me.

I offend them all really. My long time theist friend from childhood was recently trying to explain to me where Islam came from. Of course, he used his bible and told me of Abraham having a child with his hand maiden because Sarah was unable to produce a child at that time. He says :
This was against god's plan but there was nothing god could do about it.

I kept my mouth shut but this all knowing god was not able to do anything about it. I'm not surprised! This same god cannot do anything else either!

Questions about their beliefs?
First, I try not to ask things just so I can point out how wrong/crazy they are. I’ve had people do that to me, and if they can’t keep from proselytizing, I avoid talking to them. If I’m truly curious, I’m more likely to Google, lol.
I accept that I don’t know everything; that respect is a two way street; the best fights are ones I don’t have to have.
I had a xtian who asked me a question, and she got offended at MY answer.
The question: ‘but if you don’t believe, where will you spend Eternity?’
My answer: ‘same place as you’.
She didn’t get it, and I gave up.

If the question offends them; it's probably because the truth is inconsistent with their belief. I have no problem shaking the foundations of their fairytales.

"Sorry. I didn't mean to offend you. I was just asking an honest question."
