Sorry to dump this out here, but I have dealt with this shit since I was a teen and I'm mad tonight about some other shit.
That's because they think everyone who isn't hardcore christian is unhappy and questioning their choices every day, just waiting on god to help.
I'm hard agnostic. That doesn't mean I'm questioning. That means I believe that we can't possibly know any more than a bacteria can fathom what I am. They're convinced that means I'm not sure if their god exists and I desperately want them to show me the light.
You know how I know what they think? It's how I was raised. It's the literal words that came out of their mouths. Luckily it's been years since anyone other than a Jehovah's Witness tried to convert me to anything and I just tell them "I think god is dead so I'm trying to get on Satan's good side by having sex outside of marriage and killing. Which do you prefer?"
I think a lot of people get agnostic twisted, but I'm not one to gatekeep people's beliefs so they can do what they like. I think a lot of folks would file me under atheism pretty quickly if I started talking, except I ain't really talking.
