Because it's Bullshit

That must give you a bit of hope.

Why are all Jehovah's witness women flat-chested?
(Visualize pushing motion) " Get off my porch!" "Get off my porch!"

When they come to my door, I tell them that i'm not religious and have no need for it, but in a cordial way. If / when they press the topic, I let them in. We always have a friendly discussion, though they tend to paint a very grim picture of the state of the world. In response, I paint what I view as a more accurate picture, using tools like gapminder.org, the effective altruism movement, etc. I find that data really surprises them, which only makes sense, as it still often surprises me.

Once, after we said our goodbyes, I overheard them talking as they walked down my driveway. One said "Wow, that guy was an atheist?" The other responded, "Yeah, and he wasn't a jerk!" I felt really nice afterwards

It is a good question. I would have asked them to pray for whirled peas.

so some young people felt committed enough in their beliefs to try spreading the word and you used it as time for bullsh!t? why didnt you engage them instead? scared they might convince you of something?? you don't know what path they traveled to get to that point so who are you to ridicule them??? ONE goal, many paths.

I love it when religious people come to my door. I get to lecture them on anything I want from environmentalism to politics. It's my home. I do the talking. I only get upset when they send their grade school children to proselytize.
