You liked Joanies common sense as I did also.
So what is your take on my tinfoil?
My childrens grandmother on the other side has alzheimers now. I have heard both of my children discussing the fact that they are in line to inherit this disease.
It could be that Ron R. is obsessed with the thought of inheriting this disease. Also, Nancy could be afraid that her children may inherit alzheimers. To me this is the reason for them to be for fetal stem cell research knowing that adult stem cell does not hold a cure for alzheimers.
I don't think your theory is "tinfoil" at all. I think it's pretty certain that their (at least Ron's) motives are purely self-centered, so your theory sounds totally possible.
