The first is a factual statement (is versus ought); The second semi-factual ("not justified" is a maybe subjective distinction); The last is purely subjective, both in the "shouldn't" and the somewhat vague definition of "mental disorder". That said, the furore around TS seems to be as much about enforcing terminology that appears to muddy-the-waters wrt biology i.e. what "woman" means, or should mean.
