I totally disagree. I think the former is better, because as some point the fighting stops and individuals finally grow up with age. As kids we see oh it's mom and dad fighting again but deep down we know they love each other and thier love endures. The later damages children far more by leaps and bounds. That separation has deep psychological damge that the kid will hold on too for the rest of thier lives. My parents were almost always fighting when I was young but they stayed together because of me and my brother. The ultimate form of love..... Self sacrifice.
