I didn’t call your belief against surrogacy ignorant zealotry. To be a Catholic means that you abide by Catholic tenets. I respect that.
I equate modern reproductive technology with modern medical technology. You (and others on this thread) do not. The danger lies in that some people might use that opinion to try to have reproductive technology outlawed. IMO, that would be equivalent to outlawing the use of blood transfusions because the Jehovah’s Witnesses believe it’s against God’s will to use them.
That doesn't even make sense. To set you straight, I have no problem equating "modern reproductive technology with modern medical technology." What I do not do is automatically assume employment of modern technology of any kind results in a morally-positive outcome.
And while it's true that as a Catholic I am opposed to IVF (while understanding many other Christians are not), that's not even what we are talking about here. We are talking about surrogacy in creating new human life.
You seem to be conflating this very specific objection to this one use of "modern medical technolgy" with the use of "modern medical technology," generally.
I wish you would stop.
Surrogacy is illegal in such religion-ridden backwaters as Japan, France, and . . . Sweden! And renting a womb is NOT an example of "modern technology." Rich people did stuff like that way long ago.
