I definitely have. It's usually when people explain capitalism the way it's sold to us (like enlightened self interest or misquoted excerpts from the wealth of nations), or with economics bs strapped to the top of it. It's always "well it's not like I want people to starve..."

But then when you remind them "hey, there's more than enough food, and the whole economic system is made up by humans" they treat you like a child for not understanding why their starting point is the only valid one
