I have little in common with my parents, who sadly absorbed the secular, almost self-hating Jewish malaise of their times even though my mother, in particular, knew better. They also know about as much regarding parenting as I do regarding how to build a perpetual motion machine. My feeling toward them is like Avraham Avinu vis-a-vis Terach; sometimes you just have to break down all their idols and lech lecho!
Indeed, frum parents who have children because Hashem commanded them to are selfless. In the secular world, parenting is often a selfish decision that stems from a desire for control and a desire to live unfulfilled dreams out through the next generation.
