Because ultimately we are being farmed by aliens who want to copy our consciousnesses to weird aliens computers that save the essence of what we were to be used like the characters on star trek use on the holodeck. They want to equate what are simulated computerized copies of consciousness with real consciousness as many who promote these ideas ARE simulated consciousness. They want it all to be accepted, for consciousnesses that Accept it can acclimatize to living in such a state, if you copied the consciousness of a person who never wanted to live that way the copy would be like that too and wish to self destruct. That, is why you are seeing trans humanism and why it is promoted positively in every avenue of society it can be, for decades.
