I just say, "oh, we're pagans," give them a weird crazy smile and close the door.

I wish I had the balls to do that. I don't like being that straightforward because I know that everybody sees them as the 'good guys' regardless of the fact that they walked onto MY property spitting THEIR bullshit down my throat. It turns into a big deal that I just don't want to deal with so I decline. OR I start debating! Which is always fun until you get tired of running in circles.

Personally, I think it is better to hit them with kindness while letting them know that we are non-believers. This way they can see that one does not need a god to be good and considerate. And, perhaps they will think twice the next time they hear about how awful non-believers are.

Invite them in to share a coffee and put on some music, maybe Monty Python - Every Sperm is Sacred should be ok

Could have said let me tell you about Satan come in lol

When someone knocks on my door the first thing they see through the glass is a 150# black jumping straight up in the air and barking like he wants to tear someone's head off. But he's a good boy.

Excellent reply.
