A core concept of transhumanism is that one can change what one is (“trans-human”: “about/over/between being a human”).
That’s also what many Social Justice Warriors and tumblr feminists believe. They make up new genders that don’t even exist and invent fantasy creatures, then they claim to have an imaginary gender (“non-binary”) or belong to a made-up species (“otherkin”), some even believe one can change one’s weight by wish (“transfat”) just by “identifying” as such.
New technologies could give them the abilities to actually become an astralgender dragon or pangendered furry duck IN REAL LIFE!
So, what if SJWs discover transhumanism? Could they take over it, become a main driving factor behind it and even make it happen but just in their twisted version?
