Where did you get physical revulsion from my post? My opposition to transgender being considered a thing is, in fact, founded on all the other grounds you cite. I'm not really impressed by science as such, so much as by facts or principles. Science can be a useful tool for determining the former or supporting the latter, but that's all that it is. When you get right down to it, by their own assertions, science is nothing more than a theoretically meticulously observed and recorded process of trial and error. Ironically, the last 150 years or so have seen it be subject to a process of mystification & glorification to the point where people wave it around like a magic wand, and popular entertainment conflates it with intelligence. If you think about it, the scientific process and logic are actually substitutes for genuine intelligence, and high level intuition. They are processes by which geniuses and insightful people teach the rest of us, or a means by which hard work can effect the results of genius. Yet nowadays, they have pretty much assumed the role of religion in society (or more specifically, the role popular entertainment and science-snobs assign to religion in their fantasy versions of human development and society), as a kind of mystery cult that gives explanations for things people don't understand, and is cited as a near-anthropomorphic authority, with dissent being treated like heresy.
