That is true, but we can and have joined with like-minded people on particular moral issues to break through the common consensus when it is immoral and make a change. We have seen this happen in a number of areas in our history including slavery and most recently abortion. They kept telling us that it was the settled law of the land and that the majority of Americans supported abortion but since Roe was overturned, we've found out that is not really the case. You can also say much the same about human child sex trafficking. Everyone knows it was happening, but it has take a series of recent events and the activism of a few to bring it more to the fore than it has been.
So, do you believe that gestational surrogacy should be illegal?
It seems to me that this is a lot more complicated than slavery and abortion.
