Yes, thermodynamici will always feel inferior to real scientists

While the thermodynamici continue to HAARP's on about Terrarists and
mass domestic swines/human crossbreeds slaying and it's other Nionist
media Nionisms they submitted themselves to.
Their feeling of inferiority is most likely permanent and
neoconservative.
