"The Bass, the River, or Shelia Mant" Airhead stereo Type

Who deserves to be called an air head? I honestly believe no one does and especially if you don't even know them. Everyone is special in there own way and no one has the right to make them feel like an air head. People gain knowledge over time and some people just learn slower but that doesn't mean anything. Were all human and no one is perfect. I feel like the only person that would ever have the right to call someone an air head is them selves because they may have known something that may have not clicked right then and there but that's about it.
