Your fallacy is that you care too much about the world. You have not seen the darkness in the world, therefore you trust it far too much. You are too naive to see how horrid the world is. But if you took off your goggles and saw how awful this world is, you would not and care for the world like you do.
You need to take your goggles off, for they hide the problems with the world. But you tell me I need to take my sunglasses off, for they make the world seem so much darker. You say the world has so much more to offer than what I am seeing. You see the world as such an amazing place and you don't understand how I cannot trust and care for the world like you do.
But maybe, maybe both of our views on the world are distorted. Maybe we're both seeing the world in a false light. Your positivity is actually very refreshing to me, and you say that my negativity makes sense to you. Maybe we could use each other's help to take off our sunglasses and goggles to see the world the way we're supposed to.
