It's getting kind of crazy in here. Did someone really just equate this issue with SLAVERY? Good, I must have imagined that...
People are using "not equivalent" interchangeably with "superior/inferior." They really don't mean the same thing, do they?
The training of a chemical engineer is not equivalent to the training of an architect. They are different professions, so they learn different things in school. There is nothing offensive about that, is there?
The training of an MD/DO is not equivalent to that of a podiatrist. Why would that statement be more offensive than the one above? Would it be less offensive if I said "the training of an MD/DO is not IDENTICAL to that of a podiatrist?" They might be equally rigorous, equally challenging, equally taxing, but they aren't equivalent, are they?
Can't we all just get along?
