People often reject the praising of motherhood at it is used as a round about way to prevent women from being full participants in the world. It's a shame to disrespect motherhood, but I get it.
The idea that women's highest purpose is to be mothers, and that that is the most appropriate activity for women, serves to hold woman back from full participation in the world. Women can, should, and for their own happiness, need, to be fully involved in the world. Indeed parenthood is one of the most beautiful things in the world and we should respect it, but not at the expense of women living full lives.
We need more involved fathers, more community, and more balance.
