Dad “The organization is a non-for profit. That means they GIVE AWAY the literature. You never have to pay for anything. That is a beauty of Jehovah’s organization.”
Clearly dad does not understand what "not-for-profit" means. Plenty of non-profits sell things.
Check out this list of the Top 100 Nonprofits on the Web.
Here are links to a couple of examples:
#3 - The Museum of Modern Art's online store: MoMA Store
#6 - Shopping at the Smithsonian
And as for the "you never have to pay for anything" comment: Who does he think pays for EVERYTHING the organization has and does? That's the hypocrisy of the organization!
It's hard to talk to people that are ignorant and refuse to reason or listen.
