A crazy and warped philosophy adopted by a fringe cult of typically smart people hell bent on dehumanizing humans in the name of so called humanity. I'm on a few Transhumanism,abolitionism, and hedonistic imperative boards just for reading the topics and getting to know what's said there and for the most part IMHO it is the academic and technological pinnacle of true misanthropy.
Transhumanism is an attempt to destigmatise Transylvanian vampires. They're not gonna get away with it. A bat, by any other name, would be a fledermaus.
