Equality is not the same as comparison. Let's review: Equality: the state of being equal Comparison: a consideration or estimate of the similarities or dissimilarities between two things or people. For example, if you said "mandatory vaccinations are equal to Hitler killing Jews" that would be an equality, and trivial to prove wrong. No vaccination is the same as the Holocaust. However, if you said "mandatory vaccinations have something in common with Hitler killing Jews" you would be able to defend that, since you could claim that one of the similarities was that people could not opt out. (Still a silly comparison, but more defensible.) See the difference there? Now let's compare the two in this situation. You claim that Sarkus equated a fetus to a wart. He did not, nor are they the same. Sarkus claimed that the definition of a growth was ambiguous, and he then compared several things that grow - cancer, a fetus, a skin cell etc. That is true. All those things grow, and that fact alone does not make any of them an individual human. See the difference there? Thus endeth today's lesson.
