From what I can tell your first sentence is that you still think PP is breaking laws even though there is 0 proof of that and the investigation has found them innocent? Then yes line up the laws and all the videos and tell me where in them you have found them breaking laws.
As far as the rest goes
I am aware that this is cheaper than adopting white children and have friends who have done this. I am aware that Utahns like having more kids than other places and feel more pressure to adopt if they cannot have their own kids. I would not compare them to the people who ran the underground railroad, but that is just me.
