I teach physical chemistry at the advanced undergraduate and graduate level, and I can assure you, I suppress dissent. People who use equations that are different from those found in the p. chem. books; people who employ 'alternative' definitions of conventional units; people who do 'non-standard' mathematics; all of them are brutally identified with a red pen and punished. Particular egregious dissenters fail the course, and in many cases this can deny them a lucrative career.
so you're saying the scientific certainty of evolution is the same as the concepts of physical chemistry. and people say that i'm brainwashed.
