The way scientists classify planets is put in place to make sense of the mess of space rocks there is in the outer solar system. It literally does not matter that pluto is classified as a dwarf planet. You wanna get mad about something? Get mad about the fact that funding for our space program has decreased by 90% since the 60s. Get mad about how thats jeopardizing our ability to learn, not only about pluto, but about a whole bunch of other stuff thats out there too!
