Opinionated Catholic has a post on breastfeeding in public that I wanted to make a quick comment on.

The problem is how we, as Americans, are culturally conditioned. Most 16 year old boys have a hard time looking at breasts, even those of nursing women, without tying it to sex. People innately knowing this are quick to assume this is the main issue. To cause another to sin

Romans 14:21 it is good not to eat meat or drink wine or do anything that causes your brother to stumble

is problematic on the part of the woman breastfeeding. In that sense to be discreet is simply being modest. Most women I know who breastfeed in public take care to cover most of the breast so that this aspect is not an issue.

The main people who are offended by breastfeeding, I find, are those who are uncomfortable with the idea of the breast being used for something other than sex. The idea of it being used to feed a child, the fruit of the natural and properly ordered marital act is challenging. Furthermore breastfeeding is hard. To tie the breasts to any act of sacrifice is even more challenging. All of this -- life, nurturing, sacrifice -- is a direct offense to the idea that breasts serve the sole and primary purpose of pleasing "me". That concept of purpose falls well within the subset of the world of selfish and non-fruit bearing sex. The real indignant response to breastfeeding comes from those who could care less whether or not they can SEE the breast.

In that sense it is a powerful ally in the cause of life.

I personally believe it should be highly encouraged because even for the abuses of some, it tells the truth about our purpose.
