I agree. I am a big supporter of traditional marriage, but at the same time I have experienced more than my fair share of disdain and condescension from fellow conservatives who assume I'm liberal because I'm unmarried or who act as though I must have something wrong with me to not be married already. I think parenting is a high calling, yet I also think that even some of us who would love to be parents may never experience it for various reasons not related to selfishness.
Might be due to what part of the country in which you live. Where I live(about an hour's away from NYC), no one really cares what your marital status is.
