I know what transhumanism is, but people who are not, for example, academics in a related field calling themselves a transhumanist makes no sense to me. Like, as a transhumanist, what do you do?
Are these people just identity-hungry fans of a genre of sci-fi? Are they saying we shouldn't work to solve societal problems because technology will do it for us? Do they just watch a lot of youtube videos about it?
Individual reactionaries identifying with transhumanism, isn't the same as transhumanism being reactionary. What I'm asking more is how the ideas of transhumanism are relevant to eugenics. The claim that "transhumanism is just eugenics with different branding" implies that the two are inseparable, and that's what I disagree with. For me, I was into it not because I secretly wanted to do eugenics, but because I thought science was cool, and I believed in unrealistic futurist fantasies because I was young and naive (and being an egg may have contributed). There are certainly valid criticisms of transhumanism from that perspective but I don't think it's correct to dismiss it as inherently reactionary or just a rebranding of eugenics.
