[blue character points at a square] We've done a peer reviewed study, and concluded that all squares have four sides
[annoyed orange character points at a diamond shape] This is objectively wrong, I've personally seen a four sided structure that isn't a square
My teacher used to tell us that all squares are rectangles, but not all rectangles are squares.
That's wrong. The yellow figure is not a rectangle.
All squares are diamonds but not all diamonds are yellow
That's a lie, I have personally seen an orange diamond.
Yeah but he said they weren't all yellow so there is room for other colors.
That's fallacious. I have personally only seen shades of yellow ranging from sea-yellow to grass-yellow
