Why it's okay to be on the wrong side of history

I'm sorry for acting aggressively

The people of history thought the time they were from is the morally right one, as we do, as our Future will think. Each of us is wrong, and it's okay to stand against our Future and the past on political and moral issues.

"An unlimited number of genetically identical individuals—the group, as well as each of its members, is called “a clone”—could be produced by nuclear transfer. In principle, any person, male or female, newborn or adult, could be cloned, and in any quantity; and because stored cells can outlive their sources, one may even clone the dead. Since cloning requires no personal involvement on the part of the person whose genetic material is used, it could easily be used to reproduce living or deceased persons without their consent—a threat to reproductive freedom that has received relatively little attention...

...the possibility of mass production of human beings, with large clones of look-alikes, compromised in their individuality; the idea of father-son or mother-daughter “twins”; the bizarre prospect of a woman bearing and rearing a genetic copy of herself, her spouse, or even her deceased father or mother; the grotesqueness of conceiving a child as an exact “replacement” for another who has died; the utilitarian creation of embryonic duplicates of oneself, to be frozen away or created when needed to provide homologous tissues or organs for transplantation; the narcissism of those who would clone themselves, and the arrogance of others who think they know who deserves to be cloned...

... Revulsion is not an argument; and some of yesterday’s repugnances are today calmly accepted—not always for the better. In some crucial cases, however, repugnance is the emotional expression of deep wisdom, beyond reason’s power completely to articulate it. Can anyone really give an argument fully adequate to the horror that is father-daughter incest (even with consent), or bestiality, or the mutilation of a corpse, or the eating of human flesh, or the rape or murder of another human being? Would anybody’s failure to give full rational justification for his revulsion at those practices make that revulsion ethically suspect?"
