Perhaps you don't understand the main current of pro-life thought. "Life is to be protected from conception to natural death." Experiments with cloning are just as much an abomination as other "reproductive technology." I think it is horrible for folks to use IVF to make embryos, but that doesn't mean that I don't want those embryos, once created, to be born.
It's a consistent mind set. It's not hard to fathom.

Do you really mean this in principle, or do you mean that it's horrible that embryos get discarded in the process as it is currently practiced?
Frankly, anyone who is opposed in principle to IVF cannot be called pro-life.
