More garbage. You are 180 degrees out of phase. Kass does not believe any such thing. You might actually try reading something he has written before attempting to lie about him.
If you think I'm exaggerating about Kass' medieval belief system, try this one:
We, on the other hand, with our dissection of cadavers, organ transplantation, cosmetic surgery, body shops, laboratory fertilization, surrogate wombs, gender-change surgery, "wanted" children, "rights over our bodies," sexual liberation, and other practices and beliefs that insist on our independence and autonomy, live more and more wholly for the here and now, subjugating everything we can to the exercise of our wills, with little respect for the nature and meaning of bodily life.
Leon R. Kass, Toward a More Natural Science
Dissection of cadavers? Organ transplantation? Laboratory fertilization? Gee, is this guy okay with anesthesia and vaccination, or is it God's duty that we die of yellow fever at age thirty, as was the custom in the time he reveres?
