Do you walk to work, or carry your lunch?
I'm sure this is clever, but I have no idea what you are talking about.
The concept, IMHO, that I don't particularly care for is lumping divorcees, widows, and un-wed mothers into one category called "single mothers" to hide the reality of their circumstance for "preventing stigmatization".
You can only be stigmatized by your own actions in these cases, so having your "feelings hurt" is a non-issue to me.
