Slippery slope

Church against technology to create human master race

If only everyone was. The real problem is that the piecewise steps towards a technology to "create [a] human master race" are so minute and have other uses. It seems okay to genetically screen for certain diseases or to have nanoscale machines and devices enter diseased cells to remove the disease. But where does that stop? Is it okay to change the color of eyes? What about the strength of muscle? What about enhancing brain power? When cosmetic surgery first appeared, proponents promoted it for uses such as removing horrible scars or accident reconstruction (note: I've had plastic surgery on my nose after a doberman took a chunk out of it). But does that justify in some sense breast implants? What if I wanted to attach another arm?
