Clearly the Palin family is very far from being such a house. They have problems which fall under regular maintenance and repairs. No need to talk to tear them down.
But we have in our society many families of bad habit and a culture that tolerates, indulges and even celebrates such habits. Families like that need the strongest of rebukes and being set apart from by the many.
Only then will such louts of families decide to better themselves.
Trying to graft goodness on a bad foundation will not work. The foundation has to be replaced first. And that means a tear down phase.
When people choose the hard path, exposing themselves to public scorn— for the sake of an innocent life— I respect that. It’s the people who murder in the shadows for selfish reasons, those are the real creeps.
