It would be nice if Dawkins or someone would produce some leaflets so I could do a swap with them. I always take theirs and I think it's only fair that I give something back.you
could produce some leaflets. I don't know. Include websites out there like talkorigins.org, skepticbible, evil-bible, WWGHA. Include the main gist of those sites, ask the JW's to visit the sites, whatever. Maybe include some books by atheists authors who make it easy to see the christian god isn't real like that they should check out. I prefer Godless
by Dan Barker. I'd stay away from the god delusion because Dawkins is a bit of a controversial figure, and IMO Dan Barker seems to have a more 'friendly' approach.
Maybe link to atheist organizations that promote science and reason, like FFRF, JREF, Center for Inquiry, etc. Maybe some youtube channels like CDK007.
I don't know. Get creative. Make your own leaflets.
