Fine, transhumanism as a simple dictionary definition devoid of all practicalities or application, ok. I see no interest in debating that point. Transhumanists all fall into the "fundamentally change humanity for the better" definition, but as soon as you dig even slightly deeper all the cracks and flaws and different interpretations of what they mean by "better" start showing. Like with any other simple dictionary definition of an ideology. There's a reason I brought up feminism as an example. Kafein's communism example is just as valid. "Communism is an ideology that considers all people as equal, regardless of race, sex, social position, etc.., and that they all deserve access to the basic neccessities of life". Using that definition only a completely irrational person would be against communism.
